Abstract
The electron-lattice interaction of NaCl:Tl+, KCl:Tl+, KBr:Tl+, and KI:Tl+ is discussed using the moments of the absorption bands. The discussion is based on a theory ofToyozawa andInoue andHonma. Consistency of the data is found for the absorption measurements. An analysis of the band shift under applied stress shows for theA-band in KCl and KBr and for theA- andB-band in KI that the electronlattice coupling constants derived from these data assuming next neighbour interaction differ considerably from those derived from the second moments of the bands.

We are also endebted to Dr. N.Terzi, Dr. E.Mulazzi, Dr. M.Sangster, and Dr. K.Cho for helpful discussions. The Tl+-doped crystals were grown by the Frankfurt Unit for Crystal Growth. The experimental part of this work was supported by the Deutsche Forschungsgemeinschaft.
