The zero field splitting in V 2+ doped NaCl, KCl, and RbCl is temperature dependent and has a shallow minimum near 50 K. Previously reported experiments are compared with theoretical results based on an anisotropic continuum phonon model. The qualitative behaviour of the spin‐Hamiltonian constant D as well as the quantitative agreement of the coefficients, which determine D as a function of temperature, are discussed.
