Abstract

High-resolution Fourier transform infrared spectrum of H2S was recorded and analyzed in the region of the v = v1 +1/2 v2 + v1 = 3.5 polyad. More than 450 transitions were assigned to the 3v1 + v2 and 21 + v2 + v3 bands with the maximum values of quantum numbers J and Ka equal to 14, 7, and 14, 9 for these two bands, respectively. The theoretical analysis was fulfilled with the Hamiltonian which takes into account strong resonance interactions among the studied vibrational states (3 1 0), (2 1 1), and also "dark" states (0 3 2) and (2 3 0). The rms deviation is 0.0019 cm -. The intensity borrowing effect in the doublets in the P-branch transitions of the 3v1 + v2 and 2v1 + V 2 + v3 bands is observed and discussed.
