摘要：

Raman scattering data are reported for Tl+ impurities in KCl, KBr, and KI. Strong lines of Eg symmetry and weaker lines of A1g, Eg, and T2g symmetry are observed. Theoretical calculations based on breathing-shell-model phonons, with no impurity-induced change in force constants, are seen to be in agreement with the data. It appears that Tl+ acts as an isotopic impurity and allows one to use the Raman effect as a direct probe of the pure-crystal phonons. © 1969 The American Physical Society.
