Abstract

Raman spectra of fullendes M6C60 (M = K, Rb, Cs) in the low energy region (20-300 cm−1) at excitation by λ = 514.5 nm and 647.1 nm are studied. One of the bands (33 cm−1 in K6C60, 45 cm−1 in Rb6C60 and Cs6C60) is assigned to the librational mode of C60 molecules while other bands are due to modes corresponding to translations of predominantly metal atoms. An analysis of the lattice dynamics of fullendes in the assumption of intermolecular potential consisting of the sum of Lennard-Jones potential (for C-C intermolecular interactions), the Born-Mayer potential (for M-C interactions) and the of the Coulomb potential has been carried out.
