摘要：

Comparisons were made for the structures of condensates from the tetramethoxysilane (TMOS)/diethoxydimethylsilane (DEDMS) system upon hydrolysis/polycondensation using infrared and Raman spectra. Spectral data indicated that all generated condensates possessed four-membered (Si-O)4 rings as structural units within their structures. Three-membered rings appeared at lower concentrations.
