Vibration-rotation interaction potential for H<sub>2</sub>O-A system

Abstract

The contact transformation method is used to derive an effective interaction potential for H₂O-A system. The expressions for the second order vibrational and rotational correction terms are obtained. The contributions of the third order, which take into account the Coriolis and Fermi resonances in H₂O molecule, are obtained too. The matrix elements of a transformed interaction potential that are necessary for calculating the broadening parameters of H₂O lines perturbed by mono-atomic gases are presented.
