Dopamine: effect of concentration and pH on the electron emission. Reaction mechanisms

Dopamine (DA) in airfree, aqueous solution (pH 7.4; 37°C) is able to emit e(-)(aq) when electronically excited in its singlet state by monochromatic UV light (λ=254 nm; 4.85 eV/hν). The quantum yield Q(e(-)(aq)), was studied in dependence of DA concentration and pH of the media. The DA transients re...
