Abstract

A novel chiroptical spectrophotometer, Multichannel (MC)-circular dichroism (CD), which does not require a wavelength scan and provides artifact-free CD spectra in seconds, was developed by solving the incompatibility problem between data acquisition and modulation timescales. The design and instrumentation are compared with the Universal Chiroptical Spectrophotometer (UCS)-1, which can measure artifact-free CD spectra in the solid state. Enantiomeric single crystals composed of achiral components, α-Ni(H₂O)₆・SO₄, and achiral films with substantial macroscopic anisotropies were measured on both MC-CD and UCS-1 and compared.

固态结构变化的快速无伪影圆二色性测量。

通过解决数据采集和调制时间尺度之间的不兼容问题，开发了一种新型的手性分光光度计，即多通道（MC）-圆二色性（CD），它不需要波长扫描，并在几秒钟内提供无伪影的CD光谱。将该设计和仪器与可测量固态无伪影CD光谱的通用Chirooptical分光光度计（UCS）-1进行了比较。由非手性成分组成的对映体单晶，α-Ni（H2 O）6・在MC-CD和UCS-1上测量并比较具有显著宏观各向异性的SiO2、SO4和非手性膜。

期刊介绍： The main aim of the journal is to publish original contributions of scientific work on the role of chirality in chemistry and biochemistry in respect to biological, chemical, materials, pharmacological, spectroscopic and physical properties. Papers on the chemistry (physiochemical, preparative synthetic, and analytical), physics, pharmacology, clinical pharmacology, toxicology, and other biological aspects of chiral molecules will be published.
