Abstract
A series of methylmethoxysilanes (tetramethoxysilane, methyltrimethoxysilane,
dimethyldimethoxysilane, and trimethylmethoxysilane) underwent hydrolysis and condensation
in aqueous solutions at circum-neutral pH while the reaction was monitored by Raman
spectroscopy. The SiO and SiC stretches of the silanes were vibrationally coupled so that a
single intense peak was observed in that region of the Raman spectra. The SiO/SiC stretch was
assigned for all of the solvated reactants and silanol intermediates and products of each hydroysis
step in solutions of low ionic strength and neutral pH. Assignments compared favorably with
vibrational frequencies calculated by a DFT method
