Inverse deuterium isotope effect in the intersystem crossing of diphenylcarbene. Report for 1984-1985
Technical Report
·
OSTI ID:7222457
The singlet-to-triplet intersystem crossing rate k/sub ST/ 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 k/sub ST/ showing both an inverse isotope effect in a given solvent as well as an inverse energy gap effect in a solvent series.
