Vibrational frequency distributions for the potassium and rubidium halides and for cesium fluoride were evaluated on the basis of the Born lattice theory by the use of Blackman s numerical sampling method. Both room-temperature and extrapolated 0°K parameters were used in the calculation. Specific heats, the corresponding Debye characteristic temperatures, and the moments of the distributions were obtained directly from the frequencies. Comparison is made with experimental data and with other theoretical work.
