95 GHz ESEEM of radical pairs: a source of radical separations and relative orientations
W-band (95 GHz) electron spin echo envelope modulation (ESEEM) is proposed as a method for simultaneously determining the relative orientation and separation of the constituents of spin-correlated radical I,airs in the solid state. The discussion focuses on the transient secondary radical pair in bacterial photosynthetic energy conversion.
