✦ Synopsis
Singlet oxygen luminescence and its vibronic coupling to the molecular modes of the crystalline host, first discovered in Cso, is shown to be present in air-exposed crystalline C ra. CT0 modes which are otherwise optically inactive are observed and found to be in good agreement with the vibrational spectrum obtained from inelastic neutron scattering. The singlet oxygen photoluminescence technique allows the vibrational eigenfrequencies to be measured from mg-sized samples. This could be of crucial importance in characterizing the other members of the fullerene family, which at present are not available in the quantities needed for neutron scattering studies.
