The temperature variations of the thermal resistivity of lithium, potassium, and rubidium is calculated within the free‐electron approximation using the anisotropic continuum dispersive model proposed by Sharma and Joshi for the lattice dynamics of metals. The theoretical results are compared with available X‐ray measurements. Except for lithium, there is reasonable good agreement between theory and experimental data.
