Abstract

The dielectric and phase properties of cyclopenthanol have been investigated using dielectric constant measurements and visual observations. As a result of these studies a model has been constructed which accounts for the observed dielectric and phase behavior in solid cyclopentanol.

From the dielectric studies three distinct solid forms have been identified in a region from the melting point at -17.5 C to -80 C. Two of these, forms I and II, are rotational phases, the third is nonrotational. The studies have concentrated on the two rotational forms and the transition between them.

The previously reported dielectric anomalies have been investigated and explained. According to the proposed model, these anomalies result from the crystal orientation within the capacitor and a dielectric anisotropy in form II of cyclopentanol. The dielectric constants along the a- and c-axes in form II have been measured.

The transformation between the two rotational forms has been identified as a nonreconstructive transformation involving molecular orientation within the crystal rather than structural changes. The kinetics of this transformation are investigated and the processes involved are discussed.
