Raman spectra of hydrogen and deuterium adsorbed on a metal–organic framework

The Raman spectra of H2 and D2 adsorbed on metal–organic framework-5 at various pressures (H2: 12.8 and 30.3 bar; D2: 2.2–24.5 bar) and temperatures (H2: 298 K; D2: 40–300 K) have been recorded. The shifts observed in the vibrational modes of the gases indicate that physisorption is responsible for the attractive interactions between the gas and the framework; these interactions are larger with respect to those detected for carbon materials.
