Abstract
The phase transition from the low- (beta) to the high-temperature (alpha) form of acetonitrile, CH(3)CN, has been directly observed and studied on a unique single crystal. Both the beta and alpha structures have been determined at temperatures close to the transition temperature (206 K and 201 K), taking advantage of the hysteresis. A single crystal of the beta form was obtained for the first time.
摘要
已在一块独特的单晶上直接观察并研究了乙腈（CH₃CN）从低温（β）到高温（α）形式的相变。利用滞后现象，在接近转变温度（206K和201K）的温度下确定了β和α结构。首次获得了β形式的单晶。
