Abstract
The transition state of a radical reaction may be treated as the point of intersection of two undisturbed potential curves, each of which characterises the energy of vibration of the atom attacked in either the initial molecule or that formed; a series of nonlinear equations of correlation has been derived for the dependence of the activation energy of a free radical abstraction reaction on the heat of reaction, the energy of triplet repulsion and the electronegativities of the atoms.
