摘要:

我们表明,结合线性吸收光谱,超瑞利散射,和理论分析,使用求和规则,以减少参数空间的大小,导致预测的双光子吸收截面的染料AF 455,同意双光子吸收光谱。我们的程序,这需要几种测量技术之间的自我一致性,不使用可调参数,提供了一种手段,用于确定严格基于实验表征的主导激发态之间的过渡时刻。我们的新方法使用求和规则和分子对称性来严格减少所需物理量的数量,这使之成为可能。

英文摘要:

We show that a combination of linear absorption spectroscopy, hyper-Rayleigh scattering, and a theoretical analysis using sum rules to reduce the size of the parameter space leads to a prediction of the two-photon absorption cross-section of the dye AF455 that agrees with two-photon absorption spectroscopy. Our procedure, which demands self-consistency between several measurement techniques and does not use adjustable parameters, provides a means for determining transition moments between the dominant excited states based strictly on experimental characterization. This is made possible by our new approach that uses sum rules and molecular symmetry to rigorously reduce the number of required physical quantities.
