Light scattering in LiCoPO₄ single crystal: analysis of the vibrational spectrum

Abstract

In a single crystal of LiCoPO₄ Raman scattering has been studied in a wide temperature range. Thirty-two of the 36 Raman-active vibrational modes predicted by group-theory analysis were detected. The experimental lines are identified on the basis of their polarization rules, frequency position, and temperature behavior.
