Temp. 29, 1140–1146 ͑September–October 2003͒ Azidoacetonitrile (N3CH2CN) and azidoacetone (N3CH2COCH3) are studied by matrix-isolation FTIR spectroscopy in solid neon, argon, and nitrogen. The IR spectra calculated using the density-fuctional theoretical method are discussed in comparison with the experimental data. Significant broadening of the recorded azide bands indicate an awkward fit of these compounds into the solid environment. The strongest absorption is observed for both compounds in the regions of asymmetric and symmetric stretches of the N3 azide group. Strong band splittings in the N3 asymmetric stretch region can be most likely explained by very strong Fermi resonances with the CN stretch and combinations and overtones of the numerous lower- frequency vibrational modes. © 2003 American Institute of Physics. ͓DOI: 10.1063/1.1619361͔ INTRODUCTION EXPERIMENTAL Sample preparation Organic azides are useful reagents in many fields.1–3 Their strongly exothermic reactions make them useful as Azidoacetonitrile was synthesized from chloroacetoni- 4 propellants.

  • Infrared Spectroscopy of Matrix-Isolated Polycyclic Aromatic Hydrocarbon Ions
    J. Phys. Chem. A 2000, 104, 3655-3669 3655 Infrared Spectroscopy of Matrix-Isolated Polycyclic Aromatic Hydrocarbon Ions. 5. PAHs Incorporating a Cyclopentadienyl Ring† D. M. Hudgins,* C. W. Bauschlicher, Jr., and L. J. Allamandola NASA Ames Research Center, MS 245-6, Moffett Field, California 94035 J. C. Fetzer CheVron Research Company, Richmond, California 94802 ReceiVed: NoVember 5, 1999; In Final Form: February 9, 2000 The matrix-isolation technique has been employed to measure the mid-infrared spectra of the ions of several polycyclic aromatic hydrocarbons whose structures incorporate a cyclopentadienyl ring. These include the cations of fluoranthene (C16H10), benzo[a]fluoranthene, benzo[b]fluoranthene, benzo[j]fluoranthene, and benzo- [k]fluoranthene (all C20H12 isomers), as well as the anions of benzo[a]fluoranthene and benzo[j]fluoranthene. With the exception of fluoranthene, which presented significant theoretical difficulties, the experimental data are compared to theoretically calculated values obtained using density functional theory (DFT) at the B3LYP/ 4-31G level. In general, there is good overall agreement between the two data sets, with the positional agreement between the experimentally measured and theoretically predicted bands somewhat better than that associated with their intensities. The results are also consistent with previous experimental studies of polycyclic aromatic hydrocarbon ions. Specifically, in both the cationic and anionic species the strongest ion bands typically cluster in the 1450 to 1300 cm-1 range, reflecting an order-of-magnitude enhancement in the CC stretching and CH in-plane bending modes between 1600 and 1100 cm-1 in these species. The aromatic CH out-of- plane bending modes, on the other hand, are usually modestly suppressed (e 2x - 5x) in the cations relative to those of the neutral species, with the nonadjacent CH modes most strongly affected.

  • A MATRIX ISOLATION SPECTROSCOPIC INVESTIGATION of the REACTION PRODUCTS of TRANSITION METAL CENTRES with ETHENE and WATER By
    A MATRIX ISOLATION SPECTROSCOPIC INVESTIGATION OF THE REACTION PRODUCTS OF TRANSITION METAL CENTRES WITH ETHENE AND WATER by MATTHEW G. K. THOMPSON A thesis submitted to the Department of Chemistry in conformity with the requirements for the degree of Doctor of Philosophy Queen’s University Kingston, Ontario, Canada November 2007 Copyright © Matthew Gary Karl Thompson, 2007 Abstract The reaction products of thermally generated atomic V with ethene and ethene isotopomers have been investigated by matrix isolation ultraviolet visible and Fourier transform infrared (FTIR) spectroscopy. When V is deposited into matrices of pure Ar, evidence for V and V2 are present in the UV-visible absorption spectra. Addition of trace amounts of ethene results in the elimination of absorptions due to V2 on deposition, likely due to the formation of … V (C2H4) van der Waals complexes on matrix condensation. Irradiation of matrices containing V and trace C2H4 in Ar, with light corresponding to atomic V electronic excitations, eliminates all UV-visible absorptions due to atomic V in the matrix. Infrared analysis of matrices containing V and C2H4 give evidence for a new product on deposition, consistent with a kinetically formed H-V-C2H3 isomer. Following further irradiation of the matrix, several new products of C-H bond insertion by the metal atom, including additional H-V-C2H3 conformational 2 isomers, and H2V(η -C2H2) products are observed in the infrared spectrum. Additionally, the formation of ethane is evident as a major product immediately following deposition of V + C2H4 + H2O in Ar. The formation of this product is consistent with alkene insertion into the V-H bond of an H-V-OH intermediate, followed by a photo-induced elimination to give C2H6.

  • Nanochemistry Views Geoffrey A
    Nanochemistry Views Geoffrey A. Ozin Nanochemistry Views Geoffrey A. Ozin Materials Chemistry and Nanochemistry Research Group, Center for Inorganic and Polymeric Nanomaterials, Chemistry Department, 80 St. George Street, University of Toronto, Toronto, Ontario, Canada M5S 3H6 After more than four and a half decades of research in the field of nanochemistry I was given the interesting opportunity to write a monthly opinion editorial for the Nano Materials Views section of the VCH-Wiley materials journals, Advanced Science, Advanced Materials, Advanced Functional Materials, Small, Particle, Advanced Engineering Materials, Advanced Optical Materials and Advanced Health Materials. This chance provided me with a superb vehicle to express opinionated and provocative views about hot button issues in nanochemistry. Dreaming up and composing these editorials has been a valuable lesson in how to write scientifically, technologically and politically correct critiques about controversial topics for a public forum, a pastime less risky for a senior scientist than a junior one. After having produced 36 of these opinion editorials on a variety of contemporary topics in nanochemistry, I thought it worthwhile to integrate them into a compendium of essays in the form of a monograph entitled Nanochemistry Views as a three score years and ten plus one, milestone in my life. I hope the reader enjoys these stories as much as I had fun writing them and at the same time learning much from knowledgeable colleagues who contributed insightful and important commentaries on my opinions, sometimes voicing heterodox views, many of which in anonymous form I included in much improved final drafts. I also received terrifically helpful editing on more-or-less every story from my talented and dynamic group of co-workers as well as excellent artistic renditions of the content of many of the stories from Wendong Wang, Chenxi Qian and ArtScientist Todd Siler.

  • Spectroscopy in Helium Nanodroplets: Studying Relaxation Mechanisms in Nature's Most Fascinating Solvent
    Spectroscopy in Helium Nanodroplets: Studying Relaxation Mechanisms in Nature’s Most Fascinating Solvent Andr´eConjusteau A DISSERTATION PRESENTED TO THE FACULTY OF PRINCETON UNIVERSITY IN CANDIDACY FOR THE DEGREE OF DOCTOR OF PHILOSOPHY RECOMMENDED FOR ACCEPTANCE BY THE DEPARTMENT OF CHEMISTRY June 2002 c Copyright by Andr´eConjusteau, 2002. All rights reserved. ii Abstract Helium nanodroplet isolation spectroscopy has recently been developed to combine materials science and chemical dynamics studies at very low temperatures. The technique, a combination of beam and matrix isolation spectroscopy, shows great promise as a tool to study both the solvent properties of superfluid helium, and the relaxation dynamics of impurities embedded in it. This thesis presents two experiments designed to improve our understanding of solvation in superfluid helium. Firstly, an experiment aimed at the formation in situ of radicals in helium nanodroplets has been performed. The photodissociation of NO2 embedded in he- lium, using a high repetition rate narrowband U.V. laser, has been attempted. The experiment led to the surprising result that, even 2000 cm−1 above the gas phase threshold, no signature of dissociation could be observed. Secondly, a predicted limitation of a successful hydrodynamic model built to explain the increase in moment of inertia of molecules solvated in helium has been probed by microwave spectroscopy. The observation of the pure rotational spectra of isotopically substituted species (HCN/DCN, and CH3F/CD3F), leads to the unequivocal conclusion that the angular velocity of the rotor greatly affects its helium–induced increase in moment of inertia. For the cyanides, it has been found iii that HCN, which is faster than DCN by 23% in the gas phase, sees its moment of inertia increase less (by 11%) than that of DCN.

Encapsulation of metal nanoparticles in polymers was studied. The metal–polymer films thus obtained exhibited satisfactory sensitivity to ammonia. Introduction isolation technique and preparative cryochemistry. The interaction of metal particles with different organic The last decade of the 20th century was marked by the and inorganic substances will be presented in the first increased attention of scientists in the fields of physics, part of this article. In the second part we will consider chemistry, material science, etc., devoted to nanoparti- the encapsulation of metal nanoparticles in polymer cles, their synthesis, properties and different reactions. films and thus obtaining the nanosystems, exhibited The reason for this lies in the fact that particles of sensor activity. nanometer size exhibit peculiar properties. At present time the most interesting subject is the connection of chemical properties of metallic particles Reactions in low temperature with their size.

  • "Carbon-Nitrogen Chain Molecules in the Laboratory and in Interstellar
    CARBON-NITROGEN CHAIN MOLECULES IN THE LABORATORY AND IN INTERSTELLAR MEDIUM BY ROBERT KOŁ OS Institute of Physical Chemistry of the Polish Academy of Sciences Warsaw 2003 ISBN 83-913520-4-8 2 to the memory of my Father 3 4 Preface Science sans conscience n’est que ruine de l’âme. –Rabelais (1532) The simplest and broadest definition of the interstellar matter – “everything but stars” – may be misleading. Is Earth a piece of it? Are humans the interstellar matter, with all material products of the terrestrial civilization? Avoiding the perils of semantics, I will rather use the term in its narrow sense. In what follows, it will primarily be applied to immense clouds of gas and dust, without which the stars would have nothing to be born from, and – when their time comes – nothing to disperse into. It is only 35 years now, since an important, yet largely unnoticed discovery has been made. The interstellar matter was found to be more than just hydrogen, helium, mineral dust, and a small admixture of heavier atoms, their ions, and few simplest diatomics – as was originally believed. In addition to this blend (not very promising for a chemist) the presence of quite complex organic molecules was revealed. By plain chemical standards, some of the compounds given the “interstellar” tag may seem bizzare (or useless), like the largest ones: rod-shaped polyacetylenic nitriles. Still, all these merit our closest attention. If a molecule is abundant enough to show up in the interstellar medium – in spite of present rudimentary detection methods – then it inevitably has to be conceived as one of most important arrangements of atoms in the Galaxy, and possibly also in the entire Universe.
