✦ Synopsis

Photochemical primary process and magnetic field effect of methyltriphenyl germane in a micelle have been investigated with the aid of a nanosecond laser-flash-photolysis technique. The germyl radical generated through triplet state was directly observed. The lifetime of the generated radical pair and the yield of the escaping germyl radical were increased with increasing magnetic field strength from 0 to 1.35 T. The yield at 1.35 T became I. 16 + 0.02 times that at 0 T.
