Abstract

(IDPC) and triplet diphenylcarbene (3DPC), the ground state, exist in rapid equilibrium during most reactions (Scheme I). 2 A pioneering flash spectroscopic study of DPC by Closs and Rabinow'has supplied an estimate of the upper limit for the equilibrium constant; however, the absolute rate constants for interconversion of the spin states of DPC were not measured due to the ultrafast rate constant (kST) of the'DPC-'DPC process, which was ...
