论文摘要
我们提出了一项实验性X射线光电子圆形二色性(PECD)研究,对C 1S边缘处的液体Fenchone。一种新型的设置,以实现液体微喷气的PECD测量[Malerz等,Rev。Sci。使用Instrum。,2022,93,015101]。对于分配给Fenchone的羰基碳的C 1S线,在向后散射平面中以固定角度获得的光电光谱的强度发现了非变化的不对称性。该实验为水溶液中有机/生物分子手性的新型探针铺平了道路。
We present an experimental X-ray photoelectron circular dichroism (PECD) study of liquid fenchone at the C 1s edge. A novel setup to enable PECD measurements on a liquid microjet [Malerz et al., Rev. Sci. Instrum., 2022, 93, 015101] was used. For the C 1s line assigned to fenchone's carbonyl carbon, a non-vanishing asymmetry is found in the intensity of photoelectron spectra acquired under a fixed angle in the backward-scattering plane. This experiment paves the way towards a novel probe of the chirality of organic/biological molecules in aqueous solution.
