✦ Synopsis

KNOWLEDGE of the effects of amine substituents on chemical shifts and coupling constants is important in elucidating the distributions of dissociable protons and rotamers in amino acids and other amine compounds at various pH values. In previous studies of 2,5-dimethylpiperazine and its hydrochloride,' we showed that for -CH,-groups having both alpha-and beta-amine substituents, a decrease
