The mutual interference between the second-derivative bands of tyrosine and tryptophan in proteins has been evaluated in terms of the ratio r between two peak-to-peak distances. The r values have been found to be well related, although not linearly, to the tyrosine/ tryptophan ratio in both model co

Second-derivative spectroscopy has been applied to the study of the fluorescence of aromatic amino acids. The spectral features of the second derivative emission spectra of free aromatic amino acids and proteins are described, the emission of each aromatic fluorophore being characterized by a partic
