Abstract: In this paper,a time resolved ESR technique has been used to study the chemically induced dynamic electron spin polarization effects of some short-lived radicals produced by the UV irradiation of benzophenone and some typical kinds of amines. The reaction mechanisms derived from this new techniqne are compatible with the static ESR method.
