摘要：

Abstract— In order to study the influence of the environment on the fluorescence of tyrosine the emission of tyrosine as well as of the related compounds p‐cresol, O‐methyltyrosine and phenylalanine in aqueous solutions of alcohol, dioxane, acetonitrile, dimethylformarnide, N‐dimethylacetamide and acetic acid was measured. It was found that the quenching of the tyrosine fluorescence by —CONH and —COOH groups proceeds apparently by direct interaction with the excited aromatic ring. The phenolic OH group does not seem to be directly involved in the process although it contributes to the quenching, probably, by increasing the electronic charge density of the excited ring. The relevant quenching constants are presented. Copyright © 1969, Wiley Blackwell. All rights reserved
