迄今为止，拉曼光学活性（ROA）仅在可见光（VIS）和近红外（NIR）光谱区域中观察到。在过去几年中，我们设计、构建并测试了第一台 ROA 仪器，该仪器在深紫外 (DUV) 光谱区域使用 244 nm 激发进行操作。这种新颖的 DUV ROA 仪器基于反向散射几何结构和入射圆偏振调制 (ICP)；它利用基于快速 DUV 成像镜头的光谱仪和专门设计的 DUV 级偏振光学器件。通过分析测量的非吸收性对映体液体样品的非共振 DUV ROA 光谱，并将这些光谱与可见光谱区记录的相应 ROA 光谱进行比较，评估了该仪器的性能。版权所有 © 2015 约翰·威利父子有限公司
Raman optical activity (ROA) has been exclusively observed in the visible (VIS) and near‐infrared (NIR) spectral regions to date. During the last few years, we have designed, constructed and tested the first ROA instrument, operating in the deep‐ultraviolet (DUV) spectral region employing 244‐nm excitation. This novel DUV ROA instrument is based on a backscattering geometry and incident circular polarization modulation (ICP); it makes use of a fast DUV imaging lens‐based spectrograph and specially designed DUV grade polarization optics. The performance of this instrument has been evaluated by analysing measured non‐resonant DUV ROA spectra of non‐absorbing enantiomeric liquid samples and by comparing these with corresponding ROA spectra recorded in the visible spectral region.
