“…It is well assessed that the nonzero D and E values of the 3 C 60 state are due to a Jahn−Teller distortion of the icosahedral symmetry I h of C 60 in its ground state. − Therefore, it is likely that the origin of the symmetry loss in the eee, t3t3t3, and T h -symmetrical hexakisadduct must be the same.…”

Transient EPR Studies of Excited Triplet States in Polyadducts of C₆₀ and Bis(ethoxycarbonyl)methylene

et al. 1997

Transient EPR spectra of the excited triplet states in polyadducts of C60 with bis(ethoxycarbonyl)methylene were measured. The equatorial−equatorial−equatorial (eee) and trans-3, trans-3, trans-3 (t3t3t3) trisadducts together with tetrakis-, pentakis-, and hexakisadduct obtained by equatorial successive addition were examined. zfs parameters D and E and spin polarization carried by the triplet species were determined by spectrum simulation. D, E values for tetrakis-, pentakis-, and hexakisadducts are very well differentiated, which makes their identification quite easy. Additionally, polarized EPR spectra of the eee and t3t3t3 trisadducts exhibit an impressive difference also in the line shape (absorption/emission polarization of eee reverts into emission/absorption for t3t3t3), accounted for by a sign reversal of D. Changes in strength of D and E values are described in terms of a simple model calculation previously applied to C60 and monoadducts.

“…Finally, to check the results of the numerical simulation, we employ the multiphonon theory 13 to calculate analyticallythe relaxation time of the excited states. We find that the relaxation time for STE is about 100 fs, which is shorter than the relaxation time of the polaron formation.…”

Relaxation process of the self-trapping exciton inC60

When C 60 is photoexcited, a self-trapping exciton ͑STE͒ is formed: The bond structure is distorted from symmetry I h to D 5d while the states A 1u and A 2u are pulled into the energy gap from highest occupied molecular orbital and lowest unoccupied molecular orbital, respectively. A dynamical scheme is employed to simulate the relaxation process of STE. The evolution of both bond structure and electronic states shows that the relaxation time to form STE is about 100 fs. It should be noted that this relaxation time is much shorter than that of charge transfer in C 60 . The origin for this large difference is discussed.
