Time-resolved ESR spectra have been observed for the lowest triplet states of s-transd,b'dimethyl-2,2'-bipyridine (s-transdmbpy), metal-free s-cis-dmbpy and [Zn(dmbpy) I'+ in rigid solutions at 77 K. The results indicate that, following the conformational change of dmbpy, the sublevel initially popu
