摘要: Abstract The vibrational spectra (infrared and Raman) of 1,3,5-cycloheptatriene have been obtained as functions temperature. bands in the were broad showed no splitting over entire temperature range investigated, 47 to 235 K, indicating that solid is disordered down K. Except for some differences linewidth, there was little change at phase transition 154 Unusual behaviour observed both phases found broaden with decreasing low-frequency Raman spectrum K contained two bands, which characteristic a glassy crystal. A band high-temperature phase, anisotropic reorientation occurring on experimental time scale.
