Abstract

Transient absorption spectra are obtained after photoexcitation of the reduced form of nicotinamide adenine dinucleotide (NADH) and are identified as due to a solvated electron (eaq-) based on comparison with known spectra and the observation of the same transient upon photolysis of N-propyl-1,4-dihydronicotinamide. The risetime of the photogenerated transient is 40 ps, with no perceptible decay within 2 ns following excitation. The quantum yield of solvated electron formation is estimated as 0.46 ± 0.20.
