摘要

摘要分析了植物和细菌类胡萝卜素（神经红素、球形红素、番茄红素、螺旋黄素、β-胡萝卜素、叶黄素、ζ-胡萝卜素、α-胡萝卜素和γ-胡萝卜素）的实验拉曼光谱和基于密度泛函理论的计算拉曼光谱。首次描述了类胡萝卜素拉曼光谱的一些特征，这使得确定分子末端基团的结构和区分它们的异构体成为可能。

New Markers for Determining the Chemical and Isomeric Composition of Carotenoids by Raman Spectroscopy

Abstract

The experimental and calculated on the basis of density functional theory Raman spectra of plant and bacterial carotenoids (neurosporene, spheroidene, lycopene, spirilloxanthin, β-carotene, lutein, ζ-carotene, α-carotene, and γ-carotene) are analyzed. A number of characteristic features in the Raman spectra of carotenoids are described for the first time, which make it possible to determine the structure of the end groups of molecules and to distinguish their isomers.

期刊介绍： Doklady Physics is a journal that publishes new research in physics of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
