Abstract
A phase transformation of normal hexadecanamide (C 15 H 31 CONH 2 ) in which the crossed hydrocarbon chain configuration changes into the parallel-chain one is investigated by means of X-rays, thermal analysis, infrared absorption and proton magnetic resonance absorption. Based upon the knowledge of the crystal structure and X-ray observation, a mechanism of successive reorientation of the hydrocarbon chain at this transformation is proposed. The twisting vibration of the hydrocarbon chain is found to play an important role for this transformation.
