- Abstract
FTIR spectroscopy was used to study the vibrational behavior of the H bond system of the H3O2- unit, present with widely varying O-H...O distances in natrochalcite-type compds., MeCu2(H3O2)(ZO4)2 (Me = Na, K; Z = S, Se). Absorption bands of powder and polarized single-crystal spectra of nondeuterated and partially deuterated natrochalcite phases are assigned to stretching and bending modes of clearly divided OH and H2O groups. These results are indicative for a noncentrosym. configuration of the H3O2- unit and confirm the presence of a very strong H bond with a split H atom position.
