✦ Synopsis

Time-resolved fluorescence depolarisation spectroscopy was used for measuring rotational reorientation times ( 7r) of C& and C,,, in toluene as a function of temperature. The anisotropy decay could not be monitored at any temperature (296-l 91 K) . The plausible reasons could be either washing off anisotropy due to the presence of Jahn-Teller active modes in excited states T,, and T, or an inverse viscosity effect phenomena.

The triplet states of C6,, and C,,, (fullerenes) in solid phase at 3 and 77 K are detected by the time-resolved EPR technique. The observed time-resolved EPR spectra and the time profiles of the transient signals indicate that the geometries of Cw and CT0 are distorted from the soccerball geometry (
