  The thermal conductivity of some orientational glasses of protonated C2H5OH
and deuterated C2D5OD ethanol, cyclic substances (cyclohexanol C6H11OH,
cyanocyclohexane C6H11CN, cyclohexene C6H10), and freon 112 (CFCl2)2 have been
analyzed in the temperature interval 2-130 K. The investigated substances
demonstrate new effects concerned with the physics of disordered systems.
Universal temperature dependences of the thermal conductivity of molecular
orientational glasses have been revealed. At low temperatures, the thermal
conductivity exhibits a universal behavior that can be described by the soft
potential model. At relatively high temperatures, the thermal conductivity has
a smeared maximum and than decreases with increase in the temperature, which
occurs typically in crystalline structures.
