摘要：

The utility of infrared and Raman spectroscopy in the characterization of powdered samples is illustrated for the case of TiO//2 (rutile). Particle shape and state of aggregation of the microcrystals are shown to have a strong effect on the infrared powder spectra as predicted by the Theory of the Average Dielectric Constant. On the other hand, surface effects related to particle size can be observed in the Raman spectra by the appearance of new bands as the surface to volume ratio increases. Finally, it is shown that the nonstoichiometric character of rutile does not have a significant effect in the infrared powder spectra.
