✦ Synopsis


In the course of a general study of fluorescence in poly-a-amino acids containing tyrosine or tryptophan, we observed a new emission band. This band was observed in poly-L-tyrosine, poly-L-tryptophan, and in copolymers of tyrosine with glutamic acid or lysine. The presence of this band depends on the conformation of the polymer in the case of poly-~tyrosine, and is seen only in the helical structure. This is illustrated in
