Abstract
Structural determination of tetramethoxysilane-derived sol-gel solutions was undertaken with ATR FT-IR. The ATR sampling method provided in-situ and almost real-time analysis. This experimental technique permitted the continuous examination of the sol-gel process throughout its initial stages. The conversion of the starting material, the formation of methanol, and the development of various functional groups were observed. Based on model silica sol-gel compounds, the AM1 quantum mechanical computational method was applied in order to determine the favored condensation products. Cyclic oligomers are preferred over chains for larger condensation products. Theoretical vibrational frequencies were obtained for these model compounds as well. Correlation of the computational results with experimental compounds were made.
