The influetrce of sokent viscosity and an external magnetic field on the rate c0nstar.t of efectronic energy transfer from triplet bcntophenone to the ketyl radical is studied; it is concluded that the transfer is mediated by electron exchange.

โฆ Synopsis
The radical yield in the electron-transfer reaction between thionine triplet and aniline in reversed micelles is increased by an external magnetic field. The saturation value of the effect amounts to 85% (18 kG) and the B1/2 value is 300 G. The magnetic-field effect is discussed on the basis of the radical-pair mechanism with a quantitative consideration of the hyperfmeinduced spin motion.
