Abstract

C60 is a new nano-molecule with many important physical and chemical properties. General Raman spectrum is used to measure the vibrational properties, which can identify the structure of its molecule and the bonding relationship between atoms. Based on the principle of molecular mechanics, the paper proposes a computational element to describe the force and energy relation of a C-C covalent bond, termed Carbon-Carbon Bonding Element (CCBE). Some focuses are put on the coordinate transformation of CCBE when modeling. The vibrational modes of C60 nano-molecule are investigated via CCBE. The resulted modes: Ag(1), Ag(2), Hg(1), are totally present, which are compared with those by group theory and Raman experiment. It is verified that the CCBE is an effective and practical method.
