The variation of dipole moment, vibrational spacings. and rotational constant with vibrational excitation is calculated for the eight halides of K and Cs, employing a polarizable ion pair model due to Rittner. The results compare well with available experimental data.
## Abstract HyperβRaman scattering by the zoneβcentre optical phonons of alkali metal halides is described in terms of an anharmonic shell model. In order to reproduce the measured relative values of the hyperβRaman tensor elements, three types of fourthβorder coupling parameters, representing intr
