Raman active normal vibrations of lanthanide oxychlorides

Abstract

Raman spectra of solid state lanthanide oxychlorides, LnOCl, where Ln  La, Pr, Nd, Sm, Eu, Gd, Dy, Ho and Er, have been measured in the 1000-40 cm −1 region and the observed fundamental wavenumbers have been assigned and discussed by referring to the results of the factor group analysis and the normal coordinate calculations based on a tetragonal space group D 7 4 h .
