The development of tandem ion mobility spectroscopy (IMS) known as IMS-IMS has led to extensive research into isomerizations of isolated molecules. Many recent works have focused on the retinal chromophore which is the optical switch used in animal vision. Here, we study a shortened derivative of the chromophore, which exhibits a rich IM spectrum allowing for a detailed analysis of its isomerization pathways, and show that the longer the chromophore is, the lower the barrier energies for isomerization are.

视网膜衍生物缩短的作用和离子迁移谱

称为IMS-IMS的串联离子迁移谱(IMS)的发展导致了对分离分子的异构化的广泛研究。最近的许多工作都集中在视网膜发色团上,后者是动物视觉中使用的光学开关。在这里,我们研究了发色团的​​缩短衍生物,该衍生物表现出丰富的IM光谱,可以详细分析其异构化途径,并显示了发色团越长,异构化的势垒能越低。
