Nv. Shokhirev et Eb. Krissinel, SIMPLE ANALYTICAL APPROACH TO THE DESCRIPTION OF FLASH-CIDNP FORMATION FOR ION RADICALS, Chemical physics letters, 236(3), 1995, pp. 247-252
The simple analytical expressions for the stationary bimolecular rate
constants of recombination of charged radicals in external magnetic fi
eld were obtained for the case of high magnetic field, stepwise exchan
ge integral and contact recombination. A comparison of the analytical
and the precise numerical calculations shows good accuracy of the prop
osed approach. Also discussed is the non-trivial influence of solvent
polarity and viscosity on the rate constants via singlet-triplet conve
rsion efficiency.
