On the study of XY2 (my ≪ mx) plane molecules

Abstract

The 'expanded local mode approach' derived in Ref. [1] (Ulenikov et al., Spectrochim. Acta Part A, 52 (1996) 1829) is modified in an appropriate way for the analysis of XY₂ (C_2v) molecules having an arbitrary value of the equilibrium interbond angle 2α_e. It is shown that the conditions considered allow one to estimate with good enough accuracy the harmonic frequencies (quadratic force field parameters) of a molecule on the basis of experimental information on pure rotational spectra only.
