Abstract
Pseudopotential calculations for the pressure dependence of the dielectric constants and energy-band structure of trigonal Se are presented. The calculations explain recent experimental observations of a strong pressure dependence for the optic spectra of Se. It is shown that interchain interactions and not local-field corrections are most important in describing the pressure data.Keywords
