Field-dependent proton relaxation in aqueous solutions of some manganese(II) complexes: a new interpretation.

Danuta Kruk1,2, Jozef Kowalewski3.   

Abstract

Field-dependent measurements of the paramagnetic relaxation enhancement for water protons in the presence of Mn(II) complexes ( S=5/2), reported recently, are re-interpreted using theoretical models that take into consideration the fact that the relaxation of the electron spin for S>1 is multiexponential (even in the Redfield limit) and that are valid for an arbitrary relation between the electronic Zeeman interaction and the zero-field splitting in the complex.
