The thermal conductivity of solid SF6, CHCI3, C6H6, and CCl4 was investigated by the linear-flow method under saturated vapor pressures in the temperature range from 80 K to the corresponding melting temperatures and then recalculated for a constant density of the samples.The contributions of the phonon -phonon and phonon -rotation interactions to the total thermal resis tance were separated using the modified method of reduced coordinates.It is shown that the phonon- rotation contribution to the thermal resistance of the crystals decreases as the rotational motion of the molecules attains more freedom.
