Raman spectra of three readily available C-type stoichiometric rare-earth sesquioxide powders of composition Ln2O3 are presented. Some correlations of spectra with body-cell structure and infrared absorption spectra have been made. Spectra of Eu2O3,
Dy2O3, and Tm2O3 display several new peaks that have not as yet been reported. Assignments of certain peaks to electronic Raman and resonance Raman transitions are discussed.
