“…A MARY spectrum is essentially a conventional stationary magnetic field effect (MFE) curve, the dependence of the yield of recombination fluorescence from radical ion pairs in irradiated solutions on extemal static magnetic field, with sharp lines in zero and low field due to the degeneracy of the spin energy levels of ttle pair. Similar techniques have also been implemented by other groups [9][10][11][12][13][14][15]. To amplify the weak and narrow MARY lines against the slowly changing background of the MFE, magnetic field modulation with lock-in detection of the signal and symmetric passage through zero of the field is used, producing a first-derivative experimental spectrum resembling CW ESR lines.…”

Specific MARY spectrum from radical anion of pentafluorobenzene

et al. 2006

The paper presents the first resolved experimental magnetically affected reaction yield (MARY) spectrum for a system with nonequivalent nuclei, radical anion of pentafluorobenzene. This observation dispels the common apprehension that because of a rather involved energy level layout a system with not all nuclei magnetically equivalent cannot produce resolved MARY lines in nonzero fields, and greatly increases the practical scope of level-crossing techniques for studies of spin-correlated radical pairs. The experimental finding is supported by schemes of energy levels calculated for this system.
