Broadening and Shifting of Vibrational-Rotational Lines Corresponding to the Highly Excited Rotational States of the Water Molecule

摘要

Self-pressure-induced, as well as argon- and nitrogen-induced, broadening gamma and shifting delta coefficients of vibrational-rotational lines of the water molecule have been calculated. The asymptotic behavior of the coefficients gamma and delta at J -> 42 and K_(a) -> J has been studied. For the calculation of the parameters gamma and delta, we used the wave functions obtained from the analysis of highly excited rotational states of the H_(2)O molecule with the maximal ever observed values of rotational quantum numbers J_(max) velence 42, K_(a max) velence 32. Rotational states were analyzed in the method of effective Hamiltonians using generating functions for the first eight vibrational states of the molecule.
