摘要：

The infrared, Raman and inelastic neutron scattering (INS) spectra of TSA·6H2O and TPA·6H2O are in agreement with those expected for the presence of H5O+2 ions. Force fields for different assignment schemes are compared with the observed vibrational frequencies and the INS spectral profile. All but two schemes are eliminated. Whilst low-resolution INS spectroscopy cannot distinguish between these two schemes, the orientations of the vibrational ellipsoids for one scheme are in better agreement with those reported from low-temperature crystallographic studies of the H5O+2 ion. © 1990.
