AbstractCircular dichroism (CD) has become an increasingly important tool in the study of biological molecules as it enables structural information to be obtained nondestructively on solution‐phase samples. However, sample requirements for CD are often seen as being too high with protein backbone measurements in standard cuvettes typically requiring ...

Circular Dichroism of Peptides
2013Circular dichroism measures the difference between the absorbance of left- and right-handed circularly polarized light, and can be used to monitor the secondary structure of peptides (far UV) and the tertiary structure of larger polypeptides (near UV).

Circular dichroism and magnetic circular dichroism of iron-sulfur proteins
Biochemistry, 1978Circular dichroism (CD) and magnetic circular dichroism (MCD) spectra are reported for the 2-Fe ferredoxins from Pseudomonas putida and Spirulina maxima, Chromatium HIPIP, the 4-Fe ferredoxin from Bacillus stearothermophilus, and the 8-Fe ferredoxin from Clostridium pasteurianum. The spectral range spans the near-infrared, visible, and near ultraviolet.

Photoluminescent ellipsometric circular dichroism
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2023A novel spectroscopic technique, photoluminescent ellipsometric circular dichroism (PECD), which distinguishes all radiative electronic transitions related to molecular chiral centers. Additionally, it is proposed as complementary to the ellipsometric Raman spectroscopy (ERS) technique, thus establishing a relationship between vibrational modes and ...

ChemInform Abstract: The Circular Dichroism of Carbohydrates
ChemInform, 1987Publisher Summary This chapter discusses the use of circular dichroism (CD) spectroscopy in the analysis of carbohydrates. The CD spectroscopy measures the difference in absorption between left- and right-circularly polarized light by an asymmetric molecule.

Abstract Circular dichroism (optical activity) can only be observed for chiral molecules or in the case of molecule-ligand binding only if at least one of the interacting species is chiral. This is usually true in biochemistry particularly if a biological macromolecule such as a protein/peptide is involved.

Circular Dichroism (CD) and Magnetic Circular Dichroism (MCD)
1986For reasons given in Chapter 7, ultraviolet and visible light absorption measurements offer very little information of a selective nature. Two other methods which use light in this wavelength range, optical rotatory dispersion (ORD) and circular dichroism (CD), provide evidence of a structural/stereochemical nature, although to gain such insight it is ...

[13] Infrared circular dichroism
1993Publisher Summary A dissymmetric (chiral) molecule or molecular conformation—that is, one which is not superimposable on its mirror image—exhibits a differential interaction with left and right circularly polarized radiation. Circular dichroism, the difference in absorbance of left versus right circularly polarized light, can occur for both ...

Circular Dichroism and Magnetic Circular Dichroism Studies on Methemoglobin and Its Derivatives
The Journal of Biochemistry, 1977CD and MCD spectra of human methemoglobin and its derivatives were studied with special reference to the relation of CD and MCD spectra to the magnetic moments. The intensities of MCD peaks of methemoglobin derivatives at 270 nm were inversely proportional to their magnetic susceptibility, and there was a linear relationship between magnetic ...

Circular Dichroism and Fluorescence Detected Circular Dichroism of Macromolecules [PDF]
, 1979 I will concentrate in this chapter on experimental and theoretical methods which are pertinent mainly to polymers and macromolecules. The optical properties of polymers are determined by the interactions between two or more similar chromophores. Therefore, to calculate the circular dichroism of a polymer we need the properties of the individual ...
