✦ Synopsis

The hypertine splitting constant of the methyl radiixl, produced by the y-irradiation of alkali metal acetates, decreases from that found in caesium acetate in the order potassium, sodium and Iithium. Electron spin relaxation is also affected by the presence of alkali metals, showing some correlation with the changes in the bypcrfine splitting constants. It is estimated that the intramolecular anisotropic,dipoiar interaction between the unpaired electron and the magnetic moment of the protons may be a major mechanism contributing to the electron spin relaxation, and that the variation in Tt T2 values among the metal acetate systems may be attriiuted to.the freedom of molecular motion of the methyl radicals in the metal acetates.
