Abstract
The study of the absolute line intensities in the high-resolution spectrum of the [D.sub.2][sup.34]S molecule in the range of 2300-2900 [cm.sup.-1] has been carried out for the first time. As a result of our analysis, about 800 experimental intensities of vibrational-rotational transitions have been obtained for the [v.sub.1] + [v.sub.2] and [v.sub.2] + [v.sub.3] bands, and a set of 6 parameters of the effective dipole moment has been calculated, which reproduce the initial experimental line intensities with standard deviation [d.sub.rms] = 9.7%. A list of transitions with frequencies and line intensities in the range under study has been compiled. Keywords: hydrogen sulfide, isotopologues, ro-vibrational analysis, line intensities.
