Abstract

Silica gel is considered a three-component system consisting of a silica core, hydroxyl shell, and pore-retained water. Inelastic neutron scattering was used to obtain a set of amplitude-weighted vibrational state density (AWSD) spectra of two silica gel families SG20 and SG100 with mean pore diameter of 20 and 100 Å, respectively. The AWSD spectra were factored into the components of this system. The factoring method used is based on the postulate of lack of correlation of the basis spectra. The factoring was carried out by the construction of physically significant basis spectra satisfying the zero linear correlation coefficient criterion.
