Notes:
The Raman-active lattice modes of crystalline P4Se3 at room temperature have been calculated in the rigid-body approximation by using estimated atom-atom potentials for the Se atoms. The agreement is satisfactory and reveals several types of couplings of the different degrees of freedom. The calculated lattice energy is of the correct order of magnitude. The potentials obtained show characteristic features which correlate with the presence of short Se—Se distances in the crystal.
