✦ Synopsis

Polarized Raman spectra of transition metal disilicides, (M = Nb, Ta, V, Cr), of hexagonal structure were MSi 2 measured on single crystals. The transmittance IR spectrum of a polycrystalline

Ðlm is also reported. The CrSi 2 vibrational modes are described in terms of symmetry and atomic motions. The e †ect due to the metal substitution on the spectra is discussed.
