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，开发了一种新型手性光学分光光度计——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。该设计和仪器与通用手性光学分光光度计 (UCS)-1 进行了比较，后者可以在固态下测量无伪影 CD 光谱。在MC-CD和UCS-1上对由非手性组分α-Ni(H ₂ O) ₆ ·SO ₄组成的对映体单晶和具有显着宏观各向异性的非手性薄膜进行了测量和比较。
