V6O13 microcrystalline powder was studied in an effort to resolve the
stoichiometric effects. The Raman scattering spectrum of stoichiometri
c V6O13 microcrystalline powder is reported. The results are compared
to the Raman scattering spectrum of V2O5 and VO2 polycrystalline mater
ials obtained by annealing V6O13.
