摘要：

The effect of the magnetic induction on the quantum yield of X2- (X = Cl, Br) radicals photogenerated in 249 nm flash irradiations of Co(NH3)5X2+ Was investigated at field intensities between 0 and 9 T. The quantum yield decreases with field intensity towards a minimum, phi(B)/phi(0) almost-equal-to 0.90 at 0.25 T. The quantum yield tends to recover its zero-field value as the field increases from 0.25 to 7 T. These experimental observations have been compared with magnetokinetic effects on the respective reactions of X2- radicals with Co (OH2)6(2+) and CO (Me6-[14] dieneN4)2+.
