The optical absorption of the F d center in KCl: Ca 2 + is studied by using point‐ion and ion‐size correction models. For the calculations the Gourary and Adrian wave function types I, II, III and Gaussian functions are used. The principal axes are obtained for several positions of the impurity‐vacancy dipoles, and the corresponding ground and excited states of the F d center are calculated. Good agreement with the experimental values is found for the Gourary and Adrian wave functions of type I.
