The Millimeter Wave Rotational Spectra of Carbonyl Sulfide

Abstract

Abstract The following rotational spectra of carbonyl sulfide have been accurately remeasured with a beam-absorption spectrometer: 16 O 12 C 32 S in the vibrational ground state and in the vibrational state 0 1 1 0. 16 O 12 C 34 S in the vibrational ground state. The ground state spectra of the following isotopic species have been measured with a video spectrometer: 17 O 12 C 32 S, 18 O 12 C 32 S, 16 O 13 C 32 S, 16 O 12 C 33 S, 16 O 12 C 36 S, and 16 O 13 C 34 S. Our measurements have enabled us to improve the molecular constants notably for these cases.
