类球铷反应中心低激发态激发态的双重三重态解释

Interpretation of a low-lying excited state of the reaction center of Rb.sphaeroides as a double triplet

P. O. J. Scherer, Sighart F. Fischer

摘要:

最近观察到的瞬态吸收的最低激发态的特殊对P* 在2710 cm-1被指定为一个单重态,这是由两个最低的三重态从两个二聚体的一半耦合。用INDO计算方法预测其强度。模拟耦合机制的三重态双重谱从P+和双重三重态P* 的斯塔克效应的影响进行了研究。

英文摘要:

The recently observed transient absorption of the lowest excited state of the special pair P* at 2710 cm-1 is assigned as a singlet which arises from the coupling of the two lowest triplets from the two dimer halves. INDO calculations are used to predict its intensity. The analogy of the coupling mechanism to the trip-doublet spectrum from P+ is shown and the influence of the double triplet on the Stark effect of P* is investigated.
