Abstract

Electronic energy transfer at the singlet level in poly‐DL‐phenylalanine was studied by comparing the experimental and theoretical values of the rate constants of fluorescence quenching by CCl~4~ and of energy transfer on a fluorescent acceptor (biacetyl). The fitting of the experimental and calculated values leads to a diffusion coefficient of the excitation energy of 3.8 to 4.8 × 10^−5^ cm^2^/s, consistent with 40 residues implied in the migration process.
