✦ Synopsis

The nonadiabatic ST_ transitions induced by the fluctuating (anisotropic) part of the hyperfine and Zeeman interactions are shown to make a significant contribution to the magnetic field effects in the radical pair recombination in liquids and micelles. The anisotropic Zeeman interaction induced ST_ transitions are found to cause a strong decrease in the radical yield Y and strong net electron and nuclear spin polarization at high magnetic field B. The experimentally observed dependence Y(B) is accurately described within the theory developed.
