Non-additive intermolecular forces from the spectroscopy of van der Waals trimers: far-infrared spectra and calculations on Ar2-DCl

Title:
Non-additive intermolecular forces from the spectroscopy of van der Waals trimers: far-infrared spectra and calculations on Ar2-DCl
Authors:
Elrod, Matthew J.; Saykally, Richard J.; Cooper, Adam R.; Hutson, Jeremy M.
Abstract:
The far-infrared vibration-rotation spectrum of the out-of-plane DCl bending band of Ar2-DCl is observed around 36·0 cm-1. The experimental bending frequency, rotational constants and hyperfine coupling constants are compared with the results of calculations employing both pairwise-additive and non-additive interaction potentials. As found previously for Ar2-HCl, there are substantial discrepancies between the experimental results and calculations employing a pairwise-additive potential. To explain the discrepancy it is necessary to include a non-additive term that arises from the interaction of the permanent multipoles of the DCl monomer with an overlap-induced quadrupole on Ar2. The new spectra should prove very valuable in a future determination of the non-additive contribution to the potential.
