- Аннотация: A study of IR spectra of H2O and D2O in nanoporous glass (PG) matrices with pores of different sizes has been carried out under geometric confinement. It has been established that the fraction of water with a strong H bond decreases and that with a weak H bond increases with increasing pore size in the region of 2nm < R < 6 nm. At R > 6 nm, there is no change in the structure of geometrically confined H2O and D2O. However, this effect is weaker for D2O (because of the D–O bond being stronger than the H–O bond). It has been shown that H2O molecules that form bonds with the pore surface are mainly formed of the molecules of a hydrogen bond framework, oscillations of which do not occur in phase. At the same time, such bonds with the surface of the pores in D2O are formed of the molecules of the hydrogen bond framework, oscillations of which occur in phase.
