The carotenoid molecules such as lutein play an important role in the absorption of light and the following transfer of energy during photosynthesis. However, the study of these processes by the experimental methods only is quite difficult because some of the transitions between the electronic states of carotenoids are optically forbidden and the effect of vibrational states change also must be taken into account. In the present work, electronic-vibrational states of the lutein molecule in the LHCII complex of higher plants and in the diethyl ether solution were described using the ab initio methods. For lutein of LHCII, the electronic energy transfer processes were modeled. The role of the “hot” S1 states of lutein was shown to be of great importance.

叶黄素分子的电子振动光谱和动力学。

类胡萝卜素分子(例如叶黄素)在光吸收过程中吸收光以及随后的能量转移中起着重要作用。然而,仅通过实验方法来研究这些过程是非常困难的,因为在光学上禁止类胡萝卜素的电子状态之间的某些过渡,并且还必须考虑振动状态变化的影响。在本工作中,使用从头算方法描述了高等植物LHCII复合物中和二乙醚溶液中叶黄素分子的电子振动状态。对于LHCII的叶黄素,对电子能量转移过程进行了建模。叶黄素的“热” S 1状态的作用被证明是非常重要的。
