  • What Is the Shape of the Helium Trimer? a Comparison with the Neon and Argon Trimers Dario Bressanini* and Gabriele Morosi
    ARTICLE pubs.acs.org/JPCA What Is the Shape of the Helium Trimer? A Comparison with the Neon and Argon Trimers Dario Bressanini* and Gabriele Morosi Dipartimento di Scienze Chimiche e Ambientali, Universita' dell'Insubria, Via Lucini 3, 22100 Como, Italy ABSTRACT: Despite its apparent simplicity and extensive theoretical investiga- tions, the issue of what is the shape of the helium trimer is still debated in the literature. After reviewing previous conflicting interpretations of computational studies, we introduce the angleÀangle distribution function as a tool to discuss in a simple way the shape of any trimer. We compute this function along with many different geometrical distributions using variational and diffusion Monte Carlo methods. We compare them with the corresponding ones for the neon and argon fl trimers. Our analysis shows that while Ne3 and Ar3 uctuate around an 4 equilibrium structure that is an equilateral triangle, He3 shows an extremely broad angleÀangle distribution function, and all kinds of three-atom configura- 4 tions must be taken into account in its description. Classifying He3 as either equilateral or linear or any other particular shape, as was done in the past, is not sensible, because in this case the intuitive notion of equilibrium structure is ill defined. Our results could help the interpretation of future experiments aimed at measuring the geometrical properties of the helium trimer. ’ INTRODUCTION candidate for the Efimov effect, first discussed in nuclear physics. 1 Weakly bound van der Waals noble gases clusters in the last The recent paper of Kolganova et al. provides a nice review of the literature of this field of research.

Phys. 151, 170901 (2019); doi: 10.1063/1.5126216 Submitted: 31 August 2019 • Accepted: 6 October 2019 • Published Online: 4 November 2019 John M. Herberta) AFFILIATIONS Department of Chemistry and Biochemistry, The Ohio State University, Columbus, Ohio 43210, USA a)[email protected] ABSTRACT Since the introduction of the fragment molecular orbital method 20 years ago, fragment-based approaches have occupied a small but growing niche in quantum chemistry. These methods decompose a large molecular system into subsystems small enough to be amenable to electronic structure calculations, following which the subsystem information is reassembled in order to approximate an otherwise intractable supersys- tem calculation. Fragmentation sidesteps the steep rise (with respect to system size) in the cost of ab initio calculations, replacing it with a distributed cost across numerous computer processors. Such methods are attractive, in part, because they are easily parallelizable and there- fore readily amenable to exascale computing. As such, there has been hope that distributed computing might offer the proverbial “free lunch” in quantum chemistry, with the entrée being high-level calculations on very large systems. While fragment-based quantum chemistry can count many success stories, there also exists a seedy underbelly of rarely acknowledged problems. As these methods begin to mature, it is time to have a serious conversation about what they can and cannot be expected to accomplish in the near future. Both successes and challenges are highlighted in this Perspective.

I would like to thank the Mississippi Center for Supercomputing Research for the use of their computational facilities and the research group of Dr. Gregory Tschumper for their guidance and computational assistance. Specifically, I would like to thank Eric Van Dornshuld for his continual support and advisement throughout this research project. Lastly, I would like to thank my advisor, Dr. Gregory Tschumper, for allowing me to work in his laboratory as well as providing me with a worthwhile project to fulfill this thesis requirement. iii ABSTRACT This work characterizes five stationary points of the formaldehyde dimer, (CH2O)2, two of which are minima, seven newly-identified stationary points of the formaldehyde/thioformaldehyde (mixed) dimer, CH2O/CH2S, four of which are minima, and five newly-identified stationary points of the thioformaldehyde dimer, (CH2S)2 , three of which are minima. Full geometry optimizations and corresponding harmonic vibrational frequencies were performed on CH2O and CH2S as well as each of the dimer configurations (Figures 3-5).

  • TA-02 Ion Science PID Response Factors USA V1.6.Pdf 1.43 MB
    Technical/Application Article 02 Version 1.6 19 July 2016 WRH/FD Ion Science PID Response Factors PID Response Photoionization Detectors (PIDs) respond to a broad range of organic and a few inorganic gaseous and volatile chemicals (‘volatiles’). In order for PID to respond to a volatile, the photon energy of the lamp must be greater than its ionization energy. Ion Science PIDs are available with 10.0 eV, 10.6 eV, and 11.7 eV lamps. This Technical Article lists the response factors (‘RF’s’) for over 800 volatiles with PID engaging these lamps. The RF relates the sensitivity of PID to a volatile to the sensitivity to the standard calibration gas isobutylene. The higher the RF, the lower the sensitivity. In the table ‘ZR’ means there is no response, NA that the value has not been measured (Not Available), and NV means that the compound is not volatile enough to measure accurately. For chemicals not listed, contact Ion Science for more information. Isobutylene as Reference Gas It is always most accurate to calibrate a PID directly with the compound to be measured. However, standard gas cylinders of many chemicals are not readily available, and in such cases isobutylene is the standard reference gas used to calibrate. The response of these chemicals differs to isobutylene by the factors listed in the table below. This table allows measurement of all the listed volatiles using only isobutylene for calibration. To obtain the true concentration of the target volatile chemical, multiply the apparent reading by the response factor listed in the table: True Concentration = Apparent Response x Response Factor For example, anisole has a response factor (RF) of 0.47 with a 10.6 eV lamp.

  • Few-Body Approach to Diffraction of Small Helium Clusters by Nanostructures
    Few-body approach to diffraction of small helium clusters by nanostructures1 Gerhard C. Hegerfeldt2 Institut f¨ur Theoretische Physik, Universit¨at G¨ottingen Bunsenstr. 9, 37073 G¨ottingen, Germany and Thorsten K¨ohler3 Max-Planck-Institut f¨ur Str¨omungsforschung Bunsenstr. 10, D-37073 G¨ottingen, Germany Abstract We use few-body methods to investigate the diffraction of weakly bound systems by a transmission grating. For helium dimers, He2, we obtain explicit expressions for the transition amplitude in the elastic channel. 1 1. Introduction In recent years typical optics experiments have been carried over to atoms, among them diffraction by double slits [1] and by transmission gratings which were produced by nanostructure techniques [2, 3]. The usual wave-theoretical methods of classical optics (Huygens, Kirchhoff) seem to give excellent descriptions of these experiments [4] so that apparently not much more than a good textbook on classical optics seems to be needed. This simple picture, however, has changed. Recently Sch¨ollkopf and Toennies [2, 5, 6] have performed impressive diffraction experiments with helium dimers and helium clusters consisting of up to 26 atoms. A typical diffraction pattern arXiv:quant-ph/9809031v1 11 Sep 1998 is shown in Fig. 1. The helium dimer He2, discovered a few years ago [8, 2], has an extremely low binding energy of −0.11 µeV [7], with no excited states. The binding energy is much smaller than the incident kinetic energy of typical experiments. Its diameter is estimated to be about 6 nm [9]. Present day slit widths are as low as 50 nm and a further reduction is expected.

Sci.,2017,8,5385 Manoj Kumar,‡a Jie Zhong,‡a Joseph S. Francisco*a and Xiao C. Zeng*ab We carry out Born–Oppenheimer molecular dynamic simulations to show that the reaction between the smallest Criegee intermediate, CH2OO, and hydrogen sulfide (H2S) at the air/water interface can be observed within few picoseconds. The reaction follows both concerted and stepwise mechanisms with former being the dominant reaction pathway. The concerted reaction proceeds with or without the Received 22nd April 2017 involvement of one or two nearby water molecules. An important implication of the simulation results is Accepted 9th May 2017 that the Criegee-H2S reaction can provide a novel non-photochemical pathway for the formation of DOI: 10.1039/c7sc01797a aC–S linkage in clouds and could be a new oxidation pathway for H2S in terrestrial, geothermal and rsc.li/chemical-science volcanic regions.
