| Abstract: | Raman spectra of solid CS2 were investigated between 13 and 90 K. Upon deposition, the spectra show the coexistence of crystalline and amorphous solids. The latter is eliminated through annealing. For the crystal, temperature effects on the lattice modes, ν1, ν2 and 2ν2 bands, are reported. The secondary structure of the overtone is attributed to crystal-field effects. |
