Abstract	The singlet to triplet intersystem crossing rate (&) for a series of diphenylcarbene derivatives is found to be a sensitive function of the energy splitting (AEsT), which in turn depends on the solvent polarity and on the structure ofthe carbene. A turn-over in the dependence of ksr on AEsT is found for the case of dimesitylcarbene (DMC) , where ksr is a decreasing function of AEsr. The results for DMC provide the first example of intersystem crossitig in the large gap limit for a carbene.
