Abstract

High-resolution Fourier transform infrared spectrum of H2S was recorded and analyzed in the region of the v=v1+v2/ 2+v3=3 poliad. Experimental transitions were assigned to the 3ν1, 2ν13, ν1+2ν3, 3ν3, 2ν1+2ν2, and ν1+2ν23 bands with the maximum value of quantum number J equal to 11, 14, 10, 11, 8, and 11, respectively. The theoretical analysis was fulfilled with the Hamiltonian model which takes into account numerous resonance interactions between all the mentioned vibrational states. The rms deviation of the reproduction of 510 upper energy levels (derived from more than 1550 transitions) with 75 parameters was 0.0022cm -1.
