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 (C2v) molecules having an arbitrary value of the equilibrium interbond angle 2αe. 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.
