Vacuum ultraviolet absorption spectra of solid OCS at 53 K

Abstract
Photoabsorption spectra of thin films of solid OCS were obtained in the 110–300 nm wavelength region. The absorption intensities and excitation energies of the 1Δ←1Σ+ and 1Π←1Σ+ transitions were changed in the solid, and higher energy Rydberg absorption was reduced and diffuse. Three absorption continua not normally observed in the gas phase were found at 4.3, 4.7, and 6.9 eV and assigned to the 3Σ+1Σ+, 1Δ←1Σ+, and 3Π←1Σ transitions, respectively.
