In extension of previous in vivo experiments, the effects of X irradiation on DPN were studied in vitro. No correlation between the effects on the ultraviolet absorption spectrum and on the coenzyme function of DPN was evident after irradiation at different pH values. However, the loss of coenzyme function could be correlated with the destruction of ribose and of riboside linkages. Catalase did not provide greater protection than did other proteins. It was concluded that the observed loss of DPN from irradiated cells is not due to the radiosensitivity of the DPN molecule itself.

Decarboxylation Reaction

2-Phenylethyl radicals (Ph-CH2-�CH2) were prepared by the decarboxylation reaction of 3-phenylpropanoic acid with sulfate radical ions (SO4-�) formed during the pulse radiolysis of aqueous solutions containing peroxydisulfate (S2O82-) ions. The ultraviolet absorption spectrum of the transient radicals consisted of a band centred at 309nm with an extinction coefficient of 5000 1, mol-1 cm-1. Attempts were made to form phenylethyl radicals by the electron-attachment dissociation reaction of (2-haloethy1)benzenes. Contrary to literature reports, it was found that the latter reaction does not occur in either cyclohexane, benzene or aqueous solutions of (2-chloroethyl)- and (2-bromoethyl)-benzenes.
