Free radical reactions continuous illumination

Here, MV " is methylviologen and the reaction rate of each process is denoted above. The MFEs on the formation of free radicals (Te) was measured by photostationary illumination in a continuous flow system. The observed relative MFEs (AR B)=[Ye(B)- Ye(PTY]/ Ye OTY) on the yield of photoinduced MV" radical with the four complexes (la-ld) is depicted in Fig. 12-13. This figure shows that the Te value of each complex decreases with increasing B from 0 T to 15 T and that it is almost saturated above 15 T. It is noteworthy that the AR(E) value decreases regularly for every replacement of a bipyridine ligand by a phenanthroline one.
