芳香族氨基酸质子化的光诱导动力学
Photoinduced dynamics in protonated aromatic amino acid
摘要：
紫外光诱导的质子化芳香族氨基酸的碎片已经出现在过去几年中，从一个什么都不知道的情况下，我们认为一个很好的理解的光学性质。我们将主要集中在色氨酸的情况下，这一审查。三个小组主要进行了光谱研究，一个主要参与了飞秒/皮秒范围内的激发态的动力学研究，以及从纳秒到毫秒的碎裂动力学研究。所有这些数据，以及高水平的从头计算，揭示了不同的质子化分子的电子状态后的碎裂机制的作用。
英文摘要：
UV photoinduced fragmentation of protonated aromatics amino acids have emerged the last few years, coming from a situation where nothing was known to what we think a good understanding of the optical properties. We will mainly focus this review on the tryptophan case. Three groups have mostly done spectroscopic studies and one has mainly been involved in dynamics studies of the excited states in the femtosecond/picosecond range and also in the fragmentation kinetics from nanosecond to millisecond. All these data, along with high level ab initio calculations, have shed light on the role of the different electronic states of the protonated molecules upon the fragmentation mechanisms.
