Abstract

The design and setup of a novel and simple backscatter Raman optical activity (ROA) spectrometer with incident light circular polarization (ICP) is presented, constructed from commercially available components. Incident light polarization is controlled using a combination of waveplates, compensating for unwanted birefringence and beam offsets. Realignment of the spectra in post‐processing reduced artifacts caused by spatial offsets. Spurious signals from achiral solvents like toluene and water are almost completely removed. The setup was validated by measuring references samples, including α‐pinene, carvone, and glucose in aqueous solution. The spectra show very good agreement with previously published results.

具有先进偏振控制功能的新型入射圆偏振光拉曼光学活性 (ICP-ROA) 光谱仪

本文介绍了一种新颖而简单的入射光圆偏振（ICP）反向散射拉曼光学活动（ROA）光谱仪的设计和设置。入射光偏振通过波板组合进行控制，以补偿不必要的双折射和光束偏移。在后处理中重新调整光谱，减少了空间偏移造成的伪影。几乎完全消除了来自甲苯和水等非手性溶剂的杂散信号。通过测量参考样品，包括水溶液中的α-蒎烯、香芹酮和葡萄糖，对该装置进行了验证。光谱结果与之前公布的结果非常吻合。

期刊介绍： The Journal of Raman Spectroscopy is an international journal dedicated to the publication of original research at the cutting edge of all areas of science and technology related to Raman spectroscopy. The journal seeks to be the central forum for documenting the evolution of the broadly-defined field of Raman spectroscopy that includes an increasing number of rapidly developing techniques and an ever-widening array of interdisciplinary applications. Such topics include time-resolved, coherent and non-linear Raman spectroscopies, nanostructure-based surface-enhanced and tip-enhanced Raman spectroscopies of molecules, resonance Raman to investigate the structure-function relationships and dynamics of biological molecules, linear and nonlinear Raman imaging and microscopy, biomedical applications of Raman, theoretical formalism and advances in quantum computational methodology of all forms of Raman scattering, Raman spectroscopy in archaeology and art, advances in remote Raman sensing and industrial applications, and Raman optical activity of all classes of chiral molecules.
