摘要：

IR spectra of the tetragonal modification of VO2 and of the trigonal form of V2O3 are recorded at room temperature and compared with that of V2O5. The investigated samples of the two lower-valent vanadium oxides, obtained on temperature-programmed reduction treatment, were also characterized with diffuse reflectance and electron-paramagnetic resonance spectra. The effect of atmospheric oxygen on these materials was revealed with XPS measurements and also studied with IR spectra. (C) 1997 Elsevier Science S.A.
