Fast and artifact-free circular dichroism measurement of solid-state structural changes

Chirality. 2023 Oct 5. doi: 10.1002/chir.23622. Online ahead of print.ABSTRACTA 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(H2 O)6 ・SO4 , and achiral films with substantial macroscopic anisotropies were measured on both MC-CD and UCS-1 and compared.PMID:37795624 | DOI:10.1002/chir.23622
