Abstract

The S and Q-branch Raman spectra of H₂, HD and D₂ were observed. Frequency-upshift and downshift were observed in the Q-branch spectra of single walled carbon nanotubes (SWNT) and H₂ on C₆₀. These small shifts were inconsistent with charge transfer. The frequency shifts of the Q(0) transition of H₂ adsorption were estimated by an H₂-surface potential with van der Waals and electrostatic terms.
