Salem-Rowland rules

Calculations predict that the lowest state of PN has an open-shell electronic configuration." " The Salem-Rowland Rule for ISC promoted by spin-orbit coupling (SOC) predicts that singlet to triplet relaxation will have its maximum rate when the singlet state is closed-shell. This is the case with diaryl carbenes where the absolute rate constants of ISC are in the order of Michl has recently pointed out the importance of donor-... [Pg.271]

The present basis for qualitative understanding of the structural dependence of SOC at biradicaloid geometries is an analysis by Salem and Rowland performed in the 2-in-2 model of biradical electronic structure 17]. This model has been extended and a more rigorous version of the Salem-Rowland rules has been derived by Michl [11], On the basis of this model the results of the previous section will be discussed, and finally, it will be shown how symmetry determines the essential features of SOC in l,ra-biradicals. [Pg.600]

Based on these results, Michl [11] derived the following revised formulation of the Salem-Rowland rules for large SOC between T and Sq ... [Pg.600]
