Abstract
The downfield shift of the tyrosyl proton resonances and an increased chemical shift difference between the resonances for the 2′, 6′ and 3′,5′ hydrogens in a series of deamino-oxytocin analogs modified in the disulfide bridge provide evidence for aromatic-sulfur interactions in d6 -dimethylsulfoxide solutions.Keywords
