- Using the transient hot-wire method the thermal conductivity and the heat capacity per unit volume have been measured for solid naphthalene and anthracene, and further measurements have been made for phase II of benzene. Measurements were made in the temperature range 110 K to 480 K, and at pressures up to 2.3 GPa. The results for benzene, naphthalene and anthracene are discussed in relation to available theoretical models for the temperature and density dependence of the thermal properties.

- Using the transient hot-wire method, simultaneous measurements of the thermal conductivity, λ, and the heat capacity per unit volume, ρcp, were made for solid phases I and II of benzene (C6H6). Data were obtained over the temperature range 105 K to 375 K, and at pressures up to 2.4 GPa. At 300 K, the I → II transition was sluggish, so phase I could be retained over a pressure range where it was metastable with respect to phase II. At about 1.2 GPa and 375 K, λ for phase II is detectably greater than for phase I, but at 300 K the two values are almost equal. The value of cp for phase I was found to decrease by about 10 per cent over the range 0–1 GPa and to remain essentially constant at higher pressures. Values of cp in phases I and II were found to be equal at all temperatures. The temperature and volume dependences of λ are discussed in relation to current theoretical ideas.

- The thermal conductivity has been measured for the phases: liquid, Ib, II, III and IV of CCl4 using the transient hot-wire method. Measurements were made at pressures up to 2.2 GPa, and in the temperature range 166–413 K. The thermal conductivity of the plastic crystal phase Ib was found to have features which are closely similar to those found for the plastic crystal phases of cyclopentane and cyclohexane. Phase IV of CCl4 was found to form at pressures in the region of 1 GPa — substantially lower than reported in previous work.
