Spectroscopie de vibration des dihydrates des acides complexes HSbCl6, HGaCl4, HGaBr4 étude d'ions H5O2+ peu engagés

Abstract

These dihydrates are halogenometallates of dioxonium. Their infrared and Raman spectra show that the central hydrogen bond is short and centered with a single minimum (isotopic effect). δ and γ OH vibration of that bond are very close, showing a very weak interaction with terminal H₂O groups. Furthermore, terminal vOH show that H₅O₂⁺ is quite free, with a greater liberty in the hexachloroantimonate.
