RELAXATION PROCESS OF CHARGE-TRANSFER IN C-60 - A NORMAL-MODE ANALYSIS

By normal mode analysis a novel picture of the relaxation process of c harge transfer in C-60 is discovered. It is found that after one elect ron is transferred to C-60, only a few normal modes with even parity c an be invoked. A Jahn-Teller (J-T) theorem predicts that only the A(g) and H-g modes are J-T active, while our results show that the A(g) mo de exchanges energy with the system nearly harmonically, and the H-g m ode dominates the relaxation process. This can be understood from thei r explicit eigenvectors. Implications for mode-selective chemistry and biological processes are discussed.
