摘要：

A tunable diode laser was used to perform measurements of absolute lines intensities in the ν1 fundamental of carbonyl sulfide. Spectra have also been recorded for the following isotopic species: 16O12C34S, 16O13C32S and 16O12C33S. The vibrational band strength Sv0 was calculated at 298 K. The absolute intensity for 100% of 16O12C32S species is found to be Sv0 = 29.69 ± 0.15 cm-2 atm-1 with the uncertainty covering three times the standard deviation. We have tried to determine the α-coefficient involved in the Hermann-Wallis factor F = (1 + αm + ⋯)2 and the value is found to be negligible (-5 ± 8) × 10-5. The Sv0 value obtained for the other isotopic species is very close to the normal one. © 1990.
