Transient ESR spectra have been observed for the lowest triplet states of naphthalene, quinoline (QN), quinolinium (QNH+), isoquinoline (iso-QN) and isoquinolinium (iso-QNH+) in ethanol at 77 K using a time-resolved ESR technique. With the aid of computer simulations, it is concluded that, following
