Algebraic description of anharmonic stretching vibrations

Chemical Physics 2009-10-31 v1

Abstract

A U(2) algebraic model is presented to describe stretching vibrations of XYn_n (n=2, 3, and 4) systems, where anharmonic interactions between the bond modes are considered. This model in a limit corresponds to an anharmonically coupled local mode model. As an example, the model for a molecule XY4_4 is applied to recently observed spectra of methane in both gas and liquid phases, and the results obtained are in good agreement with the experiments.
