The interaction of nanocrystalline tin oxide and titanium oxide powders with NO2-containing atmosphere has been followed as a function of temperature by Raman spectroscopy. New bands appearing in the 800-1600 cm(-1) range have been observed and attributed to various adsorbates. The responsibility of adsorbed nitrites in the sensor resistance change is proposed.

Abstract
The interaction of nanocrystalline tin oxide and titanium oxide powders with NO2-containing atmosphere has been followed as a function of temperature by Raman spectroscopy. New bands appearing in the 800-1600 cm(-1) range have been observed and attributed to various adsorbates. The responsibility of adsorbed nitrites in the sensor resistance change is proposed.
