AI Article Synopsis

  • The study examines infrared and Raman spectra of solutions in liquid argon and krypton featuring dimethyl ether and carbon dioxide isotopomers.
  • The findings provide new information about specific CO(2) resonance frequencies within the CO(2)-ether complexes.
  • Experimental data is complemented by advanced computational calculations to analyze force constants and dipole moments relevant to the observed resonances.

Article Abstract

Infrared and Raman spectra of solutions in liquid argon and krypton containing dimethyl ether or its fully deuterated isotopomer and (12)CO(2) or (13)CO(2) are investigated. The spectra lead to new data on the nu(1) (CO(2) )/2 nu(2) (CO(2) ) resonances appearing in the complex of CO(2) with the ether. The experimental data, and their interpretation, is supported by MP2/6-311++G(2d,2p) calculations of the cubic and quartic force constants and of the first and higher order dipole moment derivatives required for the modelling of the Fermi and Darling-Dennison resonances observed.

Raman spectroscopy has great potential for quantitative analysis of natural gas. Helium is one of the components of natural gas and has a wide range of applications. It was believed that noble gases could not be detected using this technique due to the absence of their vibrational spectra.

This study evaluated the structural changes of enamel treated by the Regenerate system and carbon dioxide (CO) laser against acid challenge. Thirty human enamel slabs were prepared and assigned into three groups: Group I: untreated (control); Group II: treated with the Regenerate system; and Group III exposed to CO laser. All specimens were subjected to an acid challenge (pH 4.

Multi-channel distorted-wave Born approximation for rovibrational transition rates in molecular collisions.

Theoretical Chemistry Institute for Molecules and Materials, Radboud University, Heyendaalseweg 135, 6525 AJ Nijmegen, The Netherlands.

Modeling protoplanetary disks and other interstellar media that are not in local thermal equilibrium require the knowledge of rovibrational transition rate coefficients of molecules in collision with helium and hydrogen. We present a computational method based on the numerically exact coupled-channel (CC) method for rotational transitions and a multi-channel distorted-wave Born approximation (MC-DWBA) for vibrational transitions to calculate state-to-state rate coefficients. We apply this method to the astrophysically important case of CO-He collisions, using newly computed ab initio three-dimensional potential energy surfaces for CO-He with CO distorted along the symmetric and asymmetric stretch (ν and ν) coordinates.
