Abstract
Infrared and Raman spectra of polycrystalline Y2O3 as well as polarize d Raman spectra of Y2O3 single crystals have been measured. A complete assignment of the bands is proposed. A normal coordinate analysis usi ng a generalized valence force field enabled us to fit the observed fr equencies with a satisfactory accuracy (3.5%). The calculated force co nstants are discussed and compared with those of alpha-Al2O3 exhibitin g the same atomic coordination. (C) 1995 Academic Press, Inc.
