Raman Effect in Zinc Oxide

The Raman effect in zinc oxide has been measured using the continuous helium-neon and ionized argon lasers as sources. The frequency and symmetry character of the fundamental modes have been determined. The results are: two ${E}_{2}$ vibrations at 101 and 437 ${\mathrm{cm}}^{\ensuremath{-}1}$; one transverse ${A}_{1}$ at 381 ${\mathrm{cm}}^{\ensuremath{-}1}$ and one transverse ${E}_{1}$ at 407 ${\mathrm{cm}}^{\ensuremath{-}1}$; one longitudinal ${A}_{1}$ at 574 ${\mathrm{cm}}^{\ensuremath{-}1}$ and one longitudinal ${E}_{1}$ at 583 ${\mathrm{cm}}^{\ensuremath{-}1}$.
