Реферат:
New forms for the adsorption of water on the terminal OH group of silica are suggested, with the water interacting with the O3SiOH fragment both as a proton acceptor and as a proton donor simultaneously. The energy preference for these forms with respect to the O3SiOH...OH2 one, proposed in previous quantum chemical studies, is supported by ab initio
6-31G*, 6-31G**//6-31G*, and MP2/6-31G**//6-31G* calculations. The new forms are confirmed also by comparison of their calculated vibrational frequencies with the observed ones for the adsorption complex.
