The assignment of two histidine proton resonances in the proton NMR spectrum of ribonuclease A has been made by forming a paramagnetic complex between pentaammineruthenium(II1) and the N-3 nitrogen of a single histidine residue. Reaction of chloropentaammineruthenium(III)dichloride with ribonuclease
