Capillary circular dichroism

Chirality, 2010
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 ...

Photoluminescent ellipsometric circular dichroism

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2023
A 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 ...

Circular Dichroism

2001
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 and magnetic circular dichroism of iron-sulfur proteins

Biochemistry, 1978
Circular 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.

Infrared Circular Dichroism and Linear Dichroism Spectrophotometer

Applied Optics, 1975
An instrument for the measurement of circular dichroism (CD) between 5000 cm(-1) and 750 cm(-1) is described. This instrument also can perform high precision linear dichroism measurements in the same wavelength range. A germanium photoelastic modulator having a large linear and angular aperture is used to vary the polarization of monochromatic ir light

Circular Dichroism (CD) and Magnetic Circular Dichroism (MCD)

1986
For 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 ...

Circular Dichroism of Peptides

2013
Circular 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 Azotobacter vinelandii ferredoxin I

Biochemistry, 1991
Room temperature circular dichroism (CD) and low temperature magnetic circular dichroism (MCD) spectra of air-oxidized and dithionite-reduced Azotobacter vinelandii ferredoxin I (FdI), a [( 4Fe-4S]2+/1+, [3Fe-4S]1+/0) protein, are reported. Unlike the CD of oxidized FdI, the CD of dithionite-reduced FdI exhibits significant pH dependence, consistent ...
