Simple Models for the Quick Estimation of Ground State Hydrogen Tunneling Splittings in Alcohols Cite This: Phys
PCCP View Article Online PAPER View Journal | View Issue Simple models for the quick estimation of ground state hydrogen tunneling splittings in alcohols Cite this: Phys. Chem. Chem. Phys., 2021, 23, 17591 and other compounds† Robert Medel Models for the quick estimation of energy splittings caused by coherent tunneling of hydrogen atoms are evaluated with available experimental data for alcohols and improvements are proposed. The discussed models are mathematically simple and require only results from routine quantum chemical computations, i.e. hybrid DFT calculation of the equilibrium geometry and the transition state within the harmonic approximation. A benchmark of experimental splittings spanning four orders of magnitude for 27 alcohol species is captured by three evaluated models with a mean symmetric deviation factor of 1.7, 1.5 and 1.4, respectively, i.e. the calculated values deviate on average by this factor in either direction. Limitations of the models are explored with alcohols featuring uncommon Creative Commons Attribution 3.0 Unported Licence. properties, such as an inverted conformational energy sequence, a very light molecular frame, an elevated torsional frequency, or a coupling with a second internal degree of freedom. If the splitting of either the protiated or deuterated form of an alcohol is already experimentally determined, the one of the second isotopolog can be estimated by three additional models with a mean symmetric deviation factor of 1.14, 1.19 and 1.15, respectively. It is shown that this can be achieved with a novel approach without any quantum chemical calculation by directly correlating experimental splittings of isotopologs across related species. -

Standard Methods for the Examination of Water and Wastewater
Standard Methods for the Examination of Water and Wastewater Part 1000 INTRODUCTION 1010 INTRODUCTION 1010 A. Scope and Application of Methods The procedures described in these standards are intended for the examination of waters of a wide range of quality, including water suitable for domestic or industrial supplies, surface water, ground water, cooling or circulating water, boiler water, boiler feed water, treated and untreated municipal or industrial wastewater, and saline water. The unity of the fields of water supply, receiving water quality, and wastewater treatment and disposal is recognized by presenting methods of analysis for each constituent in a single section for all types of waters. An effort has been made to present methods that apply generally. Where alternative methods are necessary for samples of different composition, the basis for selecting the most appropriate method is presented as clearly as possible. However, samples with extreme concentrations or otherwise unusual compositions or characteristics may present difficulties that preclude the direct use of these methods. Hence, some modification of a procedure may be necessary in specific instances. Whenever a procedure is modified, the analyst should state plainly the nature of modification in the report of results. Certain procedures are intended for use with sludges and sediments. Here again, the effort has been to present methods of the widest possible application, but when chemical sludges or slurries or other samples of highly unusual composition are encountered, the methods of this manual may require modification or may be inappropriate. Most of the methods included here have been endorsed by regulatory agencies. Procedural modification without formal approval may be unacceptable to a regulatory body. -

Moreover, our results are qualitatively consistent with the hypothesis Astrochemistry that high-energy condensed phase radiolysis is mediated by low-energy electron-induced reactions.

Detection of Methoxymethanol As a Photochemistry Product Of
Detection of Methoxymethanol as a Photochemistry Product of Condensed Methanol Hope Schneider,1 Anna Caldwell-Overdier,1 Sophie Coppieters ‘t Wallant,1 Lan Dau, 1 Jean Huang,1 Ifunanya Nwolah,1 Muhammad Kasule,2 Christina Buffo,1 Ella Mullikin,1 Lily Widdup,1 Aury Hay,1 Si Tong Bao,1 Jeniffer Perea,1 Mayla Thompson,1 Rhoda Tano-Menka, 1 Mileva Van Tuyl,1 Amy Wang,1 Sophia Bussey,1 Nina Sachdev,1 Christine Zhang,1 Michael C. Boyer,2 and Christopher R. Arumainayagam1* 1 Department of Chemistry, Wellesley College, Wellesley, MA 02481 2 Department of Physics, Clark University, Worcester, MA 01610 Abstract We report the identification of methoxymethanol (CH3OCH2OH) as a photochemistry product of condensed methanol (CH3OH) based on temperature-programmed desorption studies conducted following photon irradiation at energies below the ionization threshold (9.8 eV) of condensed methanol. The first detection of methoxymethanol in the interstellar medium was reported in 2017 based on data from Bands 6 and 7 from the Atacama Large Millimeter/submillimeter Array (ALMA). The cosmic synthesis of “complex” organic molecules such as methyl formate (HCOOCH3), dimethyl ether (CH3OCH3), acetic acid (CH3COOH), ethylene glycol (HOCH2CH2OH), and glycolaldehyde (HOCH2CHO) has been attributed to UV photolysis of condensed methanol found in interstellar ices. Experiments conducted in 1995 demonstrated that electron-induced radiolysis of methanol cosmic ice analogues yields methoxymethanol. In three recent publications (2016, 2017, and 2018), methoxymethanol was considered as a potential tracer for reactions induced by secondary electrons resulting from the interaction of cosmic rays with interstellar ices. However, the results presented in this study suggest that methoxymethanol can be formed from both radiation chemistry and photochemistry of condensed methanol. -

(B) REACTION CuSO45H2O(aq) + 4NH3(aq) [Cu (NH3)4]SO4H2O + 4H2O (C) PROCEDURE Take 5 gm crystalline cupric sulphate in a 250 ml beaker. Dissolve it in minimum quantity of water and then add few drops of diluted sulphuric acid. Add concentrated ammonia solution to the beaker with constant stirring, until the blue precipitate of cupric hydroxide, first formed completely dissolve to yield a clear, deep blue solution and there should be smell of ammonia in the beaker. Now add 20 ml alcohol dropwise from the dropping funnel to the beaker with constant stirring until the blue precipitates settled and clear solution is obtained. Heat it to 60o 70oC in the water bath for about 10-15 minutes. Then stop heating and remove the beaker from the water bath and allow it to stand. Long needle shaped blue crystals of tetramine cupric sulphate separates out. Filter and wash the crystals with a few drops of alcohol. Dry the crystals on a porous plate or in a desiccator. Weigh the dry crystal and find out the percentage yield followed by percentage purity by usual methods. 2.
