摘要: The width of the 1332-${\mathrm{cm}}^{\ensuremath{-}1}$ first-order Raman line in diamond, measured by Krishnan and Solin Ramdas from 15 to 970 K, varies with temperature as expected anharmonic interaction optical phonon two phonons half frequency. magnitude agrees a theoretical estimate Klemens.
