Abstract
The electron spin resonance spectra of solutions containing two differently coordinated complexes of a transition metal ion show line-broadening if interconversion of the two species occurs at the critical rate. The relaxation matrix formulation is used to discuss the lineshapes for spin ½ systems. The result, for the exchange broadening in the fast exchange limit, is the same as that obtained from the modified Bloch equations, provided that the rotational correlation times are much shorter than the lifetimes of the individual complexes.Keywords
