Absorption spectra of alkali halide crystals doped with In^+ or Sn^<++> have been investigated over the temperature range from 170 to 300K under high pressure. In the case of In^+, when the host crystal lattice of the potassium halides is converted from the NaCl-type to CsCl-type structure by the application of pressure, the separation between the A_1 and A_2 bands decreases by about 20-30%. The temperature dependence of the A band shows the characteristics of the dynamical Jahn-Teller effect in both the NaCl-type and CsCl-type structures. In the case of Sn^<++> the separation between the A_1 and A_2 bands decreases gradually with pressure. The temperature dependence of the A band under high pressure also shows the characteristics of the dynamical Jahn-Teller effect.
