Abstract

This paper reports recent progress made in FTIR investigation of high surface materials such as SiO2 by means of the transmission technique. FTIR spectroscopy provides the following advantages: (a) Improved resolution makes the correct detection of band shapes of absorptions possible which are assigned to free surface OH groups. (b) Part of the finger print region and the total of the far IR range are now accessible. (c) Difference spectra allow the detec-tion of minute changes in the surface induced by variation of physical or chemical parameters.
