Electron spin resonance study of inversion isomers of 1-fluorocyclopropyl radicals
Abstract
Inversion isomers of 1-fluoro-2,3-cis-dimethyl-cyclopropyl radicals have been observed separately by e.s.r. spectroscopy; the hyperfine splitting constant (h.f.s.c.) of the β-proton cis to the odd electron orbital is far larger than that of the trans β-proton.
