Abstract

A group-theoretical scheme - generally valid for planar CS asymetric tops - is described to predict alterations in the rotational structure of infrared bands of HNCO caused by Coriolis interactions among a′ and a″ vibrations. Through inversion parities and perturbation mixing rules it is shown how the parallel component arises in the ν6(a″) band, and that no extra features are expected for the in-plane modes. The Coriolis-triad ν456 is approximately treated as two separate pairs and the K-dependence of induced parallel rotational transitions is estimated.
