✦ Synopsis

fiuorescencc quantum yields, Y, from photoselected vibrational states in the S1 manifold of anthracene and of perdeurcratcd ~nthncene in planar supersonic jets reveal a large imerse dcuterium isotope effect on the non-radiative relaxation from the SI origin ()-H/I'D = 5). while for high (21500 cm -t) excess energies above the S, ori$n the inverse isotope effect is eroded ( ~H/YD = 1). Nobel information emerges on intermediating states involved in intersystem crossing.

The singlet-to-triplet intersystem crossing rate ( kST) of diphenylcarbene (DPC) is found to exhibit an inverse isotope effect in various solvents. An off-resonance coupling model between the initial singlet state and a sparse triplet vibronic manifold accounts for kST showing both an inverse isotop
