The phonon density of states of Rb,& has been measured above and below the superconducting phase transition temperature of 29 K and in the energy transfer range 1 < AE< 300 meV at an energy resolution AE/E= 2%. Marked changes in the molecular vibrational spectrum of C6,, are observed upon intercalat
