Jahn Teller Distortion

The low-lying states of R′ centers in LiF, KCl, and KBr have been calculated using the quasicontinuum model of F aggregate centers. It turns out that the ground state of the R′ center is of 3A2 symmetry rather than 1A1 or 1E symmetry, and that the first excited state of the R′ center to which the optical transition occurs from its ground state is an orbitally doubly degenerate state (3E). The absorption line shape for the transition 3A2 → 3E of the R′ center has also been discussed for these crystals. The reasons for the presence of common features in the R′ bands in LiF, KCl, and KBr are pointed out. A comparison of the calculated results with the experimental results shows that the R′ band is due to the transition from the ground state of the R′ center (F3− center) to its first excited state perturbed by the dynamic Jahn–Teller distortion.
