Аннотация
First data on Raman vibrational spectra of a series of sodium-deficient hydrated eudialyte group minerals which crystal structures were investigated earlier have been obtained. These spectra turned out to be much more sensitive to the presence of hydrated forms of oxonium than the IR spectra. They contain strong bands in the range of 1300–2800 cm–1, which, by quantum electronic calculations correspond to the O···O distances of ≈2.40–2.8 Å in hydrated eudialyte-related minerals. Thus, the presence of oxonium in eudialytes is confirmed not only by indirect, but also by the direct evidences.
