Using the Kellerman model of the NaCl crystal, the eigenfrequencies at 0°K are found from those at room temperature by a first-order perturbation theory, which is developed here. From this the frequency distribution at 0°K is obtained and is compared with the room-temperature frequency spectrum. The specific heat and apparent Debye temperatures below 100°K based on both distributions as well as a linearly weighted average are given.
