Abstract
A perturbation calculation is used to estimate small ground‐state singlet‐triplet splittings in large biradicals in which two triphenylmethyl groups are bridged at para positions by polyene, polyphenylene, polymethylene, or ether groups. The calculated splittings are orders of magnitude larger than the rates of spin exchange reported by Reitz and Weissman for some of these biradicals.Keywords
