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.
