Abstract

Abstract Participation of singlet molecular oxygen (1O2) in peroxidation of dopa and dopamine was studied by measurements of chemiluminescence spectra, the influence of solvents with various lifetime of O2 (1Δg) and O2 (1Δg)-quenchers on quantum yield of chemiluminescence. A decrease of absorption and fluorescence intensities of 1,3-diphenylizobenzofuran (DPBF) was also studied in the presence of dopa and dopamine oxidized with alkaline H2O2 as a criterion for the involvement of 1O2.
