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