FOURIER-TRANSFORM SPECTROSCOPY OF CARBONYL SULFIDE FROM 3700 TO 4800 CM(-1) AND SELECTION OF A LINE-POINTING PROGRAM

We have measured the Fourier transform spectrum of natural OCS from 37 00 to 4800 cm(-1) with a near Doppler resolution and a line-position a ccuracy between 4 and 8 x 10(-5) cm(-1). For the normal isotopic speci es, 37 vibrational transitions have been analyzed for both frequencies and intensities. We also report 15 bands of (OCS)-S-34, eight bands o f (OCS)-C-13, nine bands of (OCS)-S-33, and two bands of (OCS)-O-18. I mportant effective Herman-Wallis terms are explained on the basis of e igenvectors. A comparison of different line-pointing programs is also presented. (C) 1998 Academic Press.
