Ir spectra of the simplest stable proton solvates in methanol and ethanol

The spectra of (MeOH)₂H⁺ and (EtOH)₂H⁺ proton disolvates formed by strong symmetrical hydrogen bonding were separated from the multiple frustrated total internal reflection (MFTIR) IR spectra of solutions of HCl in methanol and ethanol. These spectra show a large number of rather narrow bands, exceeding the number of bands in the spectra of the pure alcohols and are in accord with a model, in which the generation of continuous absorption in solutions of strong acids is a consequence of the interaction of vibrations for protons in a strong, symmetrical hydrogen bond with the vibrations of other groups of proton disolvates.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 217–220, January, 1991.
