Effective polarizability operator for X2Y-type molecules. Application to line width and line shift calculations of H2O

Abstract

The expressions for the second-order rotational correction terms of the effective polarizability operator of asymmetric rotors have been derived using the method of contact transformation. The correction terms have been calculated for the H₂O molecule. The influence of the rotational contributions on the halfwidths and shifts of some selected lines of H₂O perturbed by the atoms of inert gases and N₂ molecule is investigated.
