Phase transitions at grain boundaries have analyzed thermodynamically in two-component systems. Possible types of phase diagrams for grain boundaries in such systems are studied. The effect of the second component on the "special grain boundary-genera1 boundary" phase transition has been examined ex

## Abstract The __E__~g~ vibration at 1268 cm^β1^ of cyclohexane is investigated by Raman scattering near the phase transition at 186 K. Within an interval of 1.5 K below the phase transition this band is split into five components with changing intensities. The spectra confirm the existence of a m
Infrared spectroscopic studies of C,O films show variation in absorbance and linewidth of the bands across the orientational phase transitions around 280 and 340 K. There is some evidence for the coexistence of phases in the 210-270 K region and for the occurrence of another transition below 200 K.
