Abstract
A seven parameter model based on a modified Urey‐Bradley potential with long range Coulomb terms is used to describe the lattice dynamics of M2XY6 compounds. Optical data are used to evaluate the force constants for the case of Cs2UBr6. The model is to be used as a starting point for a comprehensive calculation of the vibronic structure of Cs2UBr6.Keywords
