Electron spin resonance of ground-state triplet aryl cations in the photolysis of substituted arenediazonium salts at 77 K
Abstract
Suitably substituted arenediazonium salts undergo photolysis in a polymer film at 77 K to yield e.s.r. spectra characteristic of triplet states which are assigned to the corresponding aryl cations of configuration (π)5(sp2)1.
