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.
