Raman Scattering from Microcrystals of MgO

Abstract

We have observed the Raman scattering spectrum from finite crystals of MgO. Lines have been observed at 595, 719, and 1096 ${\mathrm{cm}}^{\ensuremath{-}1}$. Very good agreement is obtained between the observed lines and the lattice dynamic theory of finite crystals. However, no agreement is obtained with the macroscopic theory.
