Thermal Conductivity of Orientationally-Disordered Crystals under High Pressure

The isochoric heat conductivity in plastic phases I and II solid cyclopentane(C5H10) is investigated. Various temperature dependents of heat conductivity indicate various characteristics of a rotary motion of molecules in these phases. In phase II, the motion of the molecules has mainly character of libration, and in phase I, is close to the hindered rotation. In a phase I of cyclopentane an increase in the slope of isochoric heat conductivity with the growth of the density of samples is revealed. Such behavior of heat conductivity is not characteristic of molecular crystals and can point to a contribution of “pseudorotation” to heat transfer. In phase II, cyclopentane the behavior of heat conductivity is close to a case of strong scattering of phonons.
