Fourier transform EPR spectroscopy was employed in studying the electron transfer (ET) and the quenching mechanisms of the photoexcited triplet state of C[sub 60] (electron donor) in the presence of the electron acceptor tetracyanoethylene (TCNE) in a benzonitrile solution. The ET reaction product, which is the stable anion radical TCNE[sup [minus]], interacts with [sup 3]C[sub 60] (both detected by EPR in the liquid phase), leading to chemically induced dynamic electron polarization of TCNE[sup [minus]], via triplet-doublet mixing mechanism. 30 refs., 3 figs., 1 tab.
