title: Characterization of the two-photon absorption resonance that is due to the internal charge-transfer transition of a push pull molecule, 4-(diethylamino)-beta-nitrostyrene.
abstract: The two-photon absorption resonance that is due to the internal charge-transfer transition of an organic push-pull molecule has been characterized. A nonlinear absorption spectrum of the 4-(diethylamino)- beta-nitrostyrene molecule was measured in a tetrahydrofuran solution by optical Kerr ellipsometry. The shape and the amplitude of the two-photon absorption spectrum are well described by a model that uses the relevant one-photon absorption spectrum related to the internal charge-transfer transition.
