The dynamic aspects of the equilibria between the manganous ion and peptides or amino acids in water solution are discussed. The variations in the ESR signal intensity and in the Mn(II) electron spin relaxation time are explained in terms of inner- and outer-sphere coordination.

Abstract
The dynamic aspects of the equilibria between the manganous ion and peptides or amino acids in water solution are discussed. The variations in the ESR signal intensity and in the Mn(II) electron spin relaxation time are explained in terms of inner- and outer-sphere coordination. A dynamic model for the solvation is hypothesized and explained in terms of ESR line shapes. Nuclear spin relaxation times of the water protons are also investigated at various temperatures and ligand concentrations.
