| Abstract: | The vibrational spectra study of electron transfer of Cl - +CH 3 Cl→ClCH 3 +Cl - reaction was studied by density function theory (DFT) calculations at 6 311++G ** level. This reaction includes old bond breaking, new bond forming and electron transferring between molecules. The vibrational frequencies and vibrational modes of reactants, precursor complexs, transition state, successor complex and product were analyzed. The relationship and the change among them confirmed the breaking of bond, the formation of bond and the process of electron transfer. |
