B. Civalleri et al., VIBRATIONAL-MODES OF ISOLATED HYDROXYLS OF SILICA COMPUTED AB-INITIO IN A CLUSTER APPROACH, Chemical physics letters, 294(1-3), 1998, pp. 103-108
Adopting cage-like clusters of the hydridosilasesquisiloxane type with
four to eight Si atoms and one SiOH group to mimick the isolated hydr
oxyl of silica has allowed the DFT computation of all vibrational mode
s of the silanol group in close agreement with experiment and the defi
nite assignment of all modes. (C) 1998 Elsevier Science B.V. All right
