Chiroptical spectroscopy has evolved into a promising tool for chiral molecular structural determination in the last four decades. Determination of the absolute configurations (ACs) of bromochlorofluoromethane and [2H1,2H2,2H3]‐neopentane demonstrated the enviable advantages of chiroptical spectroscopy. Furthermore, uncovering the errors in the ACs reported in the literature established a glimpse...
We investigated the site-specific local structure of an amyloid peptide, NH 2 –GSNKGAIIGLM–COOH [Aβ(25–35)], one of the active fragments of amyloid β peptide that is known to be responsible for Alzheimer's disease, in the fibrillar aggregated state. Isotope-assisted infrared vibrational circular dichroism (VCD) and absorption (VA) spectroscopy were used for the parent Aβ(25–35) peptide, along...
Chiroptical spectroscopy is being widely used for determining the three‐dimensional molecular structures (i.e., absolute configurations and conformations) of chiral molecules. The general procedure used with any of the chiroptical spectroscopic methods is to analyze the experimental data using corresponding quantum chemical predictions. Such analysis involves multiple steps, including consideration...
