Raman spectra of polycrystalline KVO 3 have been recorded at various temperatures. Splittings have been observed for most fundamentals and the external mode region contains at least eight bands. The spectra are interpreted in terms of a group theoretical analysis based on the molecular symmetry and the known crystal structure. The frequency versus temperature plots for external modes of KVO 3 indicate that a single crystal structure exists between 10 and 300 K.
