Absorption (in the range of 420 to 750 nm), emission and excitation spectra for excitation in the range of 550 to 650 nm have been obtained. Orbitally forbidden singlet-singlet transitions are observed between 480 and 650 nm in accord with absorption spectra of $C_{60}$ in solution but with a better resolution and different matrix shifts. This last effect can be explained in terms of the different polarizabilities of the matrix atoms. High resolution absorption spectra of $C_{60}$ in Ne provide structures comparable to those of the gas phase. A triple peaked emission band (680; 720; 800 nm) is observed in Ne, Ar and Kr matrices but not in Xe matrices. While the excitation spectra of the first two peaks reproduce quite well the absorption spectra, the 800 nm emission can only be excited in the long wavelength region of the absorption spectra, suggesting that its origin is a different electronic state. en_US dc.format.extent 67736 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title SPECTROSCOPY OF $C_{60}$ IN RARE GAS MATRICES en_US dc.type article en_US
