Abstract
The far-infrared reflectivity of single-crystal GeSe2 has been measured with polarized light when E//a and E//b. Using Kramers-Kronig analysis and four-parameter semi-quantum model fits of the reflectivity data, the infrared-active TO and LO modes (phonon frequencies) and damping factors have been determined. Five reststrahlen peaks were observed for the case E//a but only one for E//b. The ratio of intralayer to interlayer force constants are discussed and appeared to be between 18 and 30.Keywords
