We made use of the Raman spectroscopy to investigate the mechanism of hydrogen adsorption on carbon materials. We have recorded the Raman active roto-vibrational Q branch of adsorbed hydrogen at various temperatures and pressures and we have developed a qualitatively theoretical model for the interpretation of the spectra. Because of the small Raman shifts observed for the Q branch we conclude that no charge transfer phenomena are involved in the interaction with the adsorbing material, but only a simple physisorption takes place; moreover, no C-H stretching signals in the region of (2800-3300) were detected, thus indicating that chemisorption, if any, should be negligible.
