WebFeb 25, 2024 · Circular dichroism (CD) spectroscopy is a useful tool used in identifying structural aspects of proteins, carbohydrates, nucleotides, peptides, DNA, etc. Because of asymmetric peptide bonds present in protein, “-NH 2 -” units of “-NH 2 -CO-” moiety influence the CD spectra in Far-UV region. WebAbstract. We demonstrate theoretically that non-chiral perovskite layers can exhibit circular dichroism (CD) in the absence of a magnetic field and without chiral activation by chiral molecules. The effect is shown to be due to splitting of helical excitonic states which can form in structures of orthorhombic or lower symmetry that exhibit ...
