在150 fs内,顺式二苯乙烯的光异构化产生的反式二苯乙烯光产物被观察到是振动热的,但具有非热的布居分布。产物的电子光谱取决于入射光子的能量。很明显,分子内振动能的再分布不是超快的。
Trans‐stilbene photoproduces appearing from the photoisomerization of cis‐stilbene within 150 fs are observed to be vibrationally hot, but with a nonthermal population distribution. The product electronic spectrum depends on the incident photon energy. Clearly, intramolecular vibrational energy redistribution is not ultrafast.
