Abstract

Photo-chemically induced nuclear magnetic polarisation has been observed in both ring and methylene protons of tyrosyl units of leucine-enkephalin and of di- and tri-L-tyrosine during optical irradiation of deuterium oxide solutions in the presence of fluoresceine type dyes. The effect is due to reversible hydrogen atom abstraction from the hydroxyl of the tyrosyl group by excited triplet dye molecules.
