The spin states unusually do not follow a Boltzmann distribution when NMR spec is used to study reactions involving these molecules.
The spin states unusually do not follow a Boltzmann distribution when NMR spec is used to study reactions involving these molecules. Two of them are combined in a colligation reaction, which can be studied with CIDNP ["kid-nip"]. The intermediate in the Barton reaction is an alkoxyl, which is one of these compounds. EPR spec can probe these substances, stable examples of which include TEMPO. Reactions involving them have initiation, propagation, and termination steps, and are depicted with fish hook arrows. They are denoted by a single dot following their chemical formula. Enzymes like superoxide dismutase prevent the formation of these substances by acting as antioxidants. For 10 points, name these highly reactive substances that have unpaired valence electrons
