Optical Absorption in C_70 and C_76: Effects of Symmetry Reduction
Abstract
Description
Optical absorption spectra of C_70 and C_76 are calculated by a tight binding model with a long ranged Coulomb interaction. The spectrum of C_70 is in overall agreement with the experiment of molecules in a solution. The variations of the spectral shape are discussed relating with the symmetry reduction from C_70 to C_76.
