Optimized geometries and total energies of some conformers of alpha- and beta-D-galactose have been calculated using the RHF/6-31G* ab initio method. Vibrational frequencies were computed at the 6-31G* level for the conformers that favor internal hydrogen bonding, in order to evaluate their enthalpies, entropies, Gibbs free energies, and then their(More)
The study of the anomeric differences observed on the spectra of methyl-alpha- and methyl-beta-D-galactopyranoside is the essential goal of this investigation. Thus, after a careful examination of the IR and Raman spectra of these two compounds, several differences in the intensities and frequency shifts are observed. This is especially noted in the region(More)
