- Abstract
- We have measured the FT spectrum of natural OCS from 4800 to 8000 cm(-1) with a near Doppler resolution and a line-position accuracy between 2 and 8 x 10(-4) cm(-1). For the normal isotopic species (OCS)-O-16-C-12-S-32, 37 vibrational transitions have been analyzed for both frequencies and intensities. We also report six bands of (OCS)-O-16-C-12-S-34, five bands of (OCS)-O-16-C-13-S-32, two bands of (OCS)-O-16-C-12-S-33 and two bands of (OCS)-O-18-C-12-S-32. important effective Herman-Wallis terms are explained by the anharmonic resonances between closely spaced states. As those results complete the study of the Fourier transform spectra of natural carbonyl sulfide from 1800 to 8000 cm(-1), a new global rovibrational analysis of (OCS)-O-16-C-12-S-32 has been performed. We have determined a set of 148 molecular parameters, and a statistical agreement is obtained with all the available experimental data. (C) 1998 Academic Press.
