High resolution vibrational-rotational spectrum of H2S in the region of the nu(2) fundamental band

The high resolution infrared spectrum of H2S has been recorded on a Fourier transform spectrometer Bruker IFS 120 HR in the region of the fundamental band nu(2) with an instrumental resolution of about 0.0020 cm(-1). Lines have been assigned to the nu(2) bands of the isotopic species (H2S)-S-32, (H2S)-S-34, and (H2S)-S-33 and in addition to the hot band 2 nu(2) - nu(2) of (H2S)-S-32. In the case of the fundamental band of (H2S)-S-32, 226 upper state energy levels with J(max) = 17 were obtained and fitted with a standard deviation of 9.96 x 10(-5) cm(-1). For (H2S)-S-34, 126 energy levels with J(max) = 14 were obtained, and for (H2S)-S-33, 57 lines could be assigned. (C) 1996 Academic Press, Inc.
