β¦ Synopsis
We calculate the vibrational density of states (VDOS) for the C6,, molecule using the recursion method. The Born potential is adopted for calculating the dynamic matrix. The results show that the peak positions of VDOS for C6e are in qualitative agreement with those of the Raman and infrared measurements.

The magnetic vibrational circular dichroism spectra of C6o fullerene in solution are presented for excitation of the 1430 and 1183 cm-l ttu-symmetry fundamental vibrations. These transitions give rise to A-term MVCD of opposite sign (A~/Do= -3.8 and l. 1 Γ 10-4, respectively) which are similar in ma
The vibrational spectrum of C6o is compared to the spectrum of a classical isotropic elastic spherical shell. We show correlations between the low frequency modes of C60 and those of the spherical shell. We find the spherical model gives the approximate frequency ordering for the low frequency modes
Based on the circulant matrix reduction theorem, the first exact solution for all the Hiickel energy levels of C,, is obtained.
Substantial electronic and vibrational interactions between solvent and C60 are revealed in the resonance Raman spectra of C60 by the appearance of bands corresponding to 11 modes that are Raman and/or IR inactive. These bands result mainly from solvent-induced rather than isotope-induced lowering o
