Abstract

A semiempirical model in the form of Pade approximants, describing vibrational-rotational (VR) interactions in intensities of VR-lines of v₂ water vapor (H₂O) band, was developed. The corresponding to the C_2v molecular symmetry group matrix elements, involved in the expansion of the transformed dipole moment, was applied to the derivation. The treatment of experimental intensities of v₂ H₂O band for transitions with ΔK = ±1 and ΔK = ±3 by means of obtained model results in decreasing the root mean square deviation (RMS) about two times (2.82 % instead of 6.20 %) in comparison to the traditional scheme.
