Fourier Transform Spectroscopy of 18O-Enriched Carbonyl Sulfide from 1825 to 2700 cm-1

We have measured the Fourier transform spectrum of carbonyl sulfide from 1825 to 2700 cm-1, using a sample enriched in both 18O (94.0%) and 17O (1.54%). A careful calibration yields a line-position accuracy between 1.5 and 3.0 10(-5) cm-1. We have observed and analyzed 118 infrared bands of which 93 are measured for the first time: 55 for 18O12C32S, 20 for 18O12C34S, 11 for 18O12C33S, 1 for 18O12C36S, 12 for 17O12C32S, 4 for 17O12C34S, 2 for 17O12C33S, and 13 for 18O13C32S. Intensities are also reported and analyzed for all those bands. The intensity accuracy is better than 10%, and the precision of approximately 1% allows us to determine some Herman-Wallis coefficients. Copyright 1998 Academic Press.
