Abstract

High-resolution Raman spectra of solutions of C₆₀in CS₂reveal the presence of¹³C isotopes in the C₆₀molecules. The observed frequency shifts for the high-energy A_g(2) totally symmetric mode can be explained in terms of first-order non-degenerate perturbation theory. Information on the frequencies of modes close to A_g(2) is obtained by studying the conditions under which a nondegenerate perturbation expansion is valid. This is done with the help of non- perturbative calculations based on first-principles and empirical vibrational models.
