Notes:
Photodarkening is reported in 4-(N,N-diethylamino)-β-nitrostyrene solutions. The photodarkening is due to the formation of new absorption bands and is thought to be a photochemical effect of the structural changes. In degenerate four-wave mixing, a resonant effect is observed around the new absorption bands but the fast response behavior does not change. After darkening, the excitation spectrum becomes complicated, which implies a multipath decay that may show the fast response in the resonant region. The solvent and concentration dependence of the darkening property is also reported. © 1997 American Institute of Physics.
