| Abstract: | ST0 type nuclear spin polarization has been observed in the reaction products of photochemically generated acylalkyl biradicals in the presence of a scavenger. From the magnetic field dependence of biradical CIDNP the rate constant k of proton abstraction from 2-methyl-2-propanethiol by the alkyl site of the biradicals has been determined (k = 5.0 × 107 M?1 s?1). |
