Abstract

The infrared spectra of hydrogen-carbonyl sulfide clusters containing paraH2, orthoH2 or HD were investigated in the 2060 cm-1 region of C-O stretching vibration. A tunable infrared diode laser spectrometer was used for the formation of these clusters in pulsed supersonic jet expansions. Some mixed clusters such as HD-HD-He-OCS and paraH2-orthoH2-OCS were also observed. The results show that the observed rotational structure corresponds to that of simple symmetric rotors, with prominent Q branches for the orthoH2 and HD clusters.
