Abstract
Data on the calorimetric, dielectric and infrared properties of a mole cular crystal cyclohexane-1,1'-diacetic acid around its 397 K ferroele ctric phase transition are presented and discussed. The DSC experiment s confirm the first order character of the phase transition and the di electric measurements reveal a relaxation soft mode in an unusually lo w frequency region 10(3)-10(4) Hz. Detailed analysis of the possible n ature of the pseudoproper ferroelectric phase transition is based on t he symmetry aspects. (C) 1998 Elsevier Science Ltd.
