โฆ Synopsis
Raman spectra (using 5 14 and 740 nm excitation) of high-purity single crystal CbO are presented for the high-and low-temperature phases, showing activity of all "gerade" modes. Within the experimental accuracy, the spectra are found to be consistent with the selection rules for Raman scattering in both the high-temperature fee and low-temperature 2a0-fee phases of solid C6,,. A complete assignment of the observed peaks is proposed.

The Raman and infrared absorption spectra of single crystal were studied. The observed CdBr 2 Raman and infrared lines were assigned to the internal vibrations of glycine molecules. The vibrational spectra show that the glycine molecule takes the form of the zwitterion in the crystal.
Raman spectra of solution-grown C6o crystals and evaporated films of C6o were measured by near-infrared laser excitation and compared with spectra of a sublimation-grown C60 crystal. Carbon disulfide and toluene were used as solutions. Broadening of the intramolecular Raman bands was observed in the
