Abstract

The infrared and Raman spectra of polycrystalline C3S2 were measured in the region from 10 to 2500 cm−1 at 85°K, and the temperature dependence of the vibrational spectra above 85°K was studied. The fundamental and first overtone of the central carbon bending mode, V7 were observed under a variety of experimental conditions including a gas phase measurement of 2v7 at 300°K. The observation of an apparent change in the sign of the anharmonicity of the v7, bending mode in going from the gas to the solid phase can be interpreted on the basis of “quasilinear” behavior for C3S2. Additional features in the vibrational spectra of C3S2 support this interpretation. A reassignment of the stretching modes of C3S2 is supported by a vibrational analysis.
