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.

Infrared Circular Dichroism and Linear Dichroism Spectrophotometer
Applied Optics, 1975An 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)
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 ...

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 Azotobacter vinelandii ferredoxin I
Biochemistry, 1991Room 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 ...

Linear Dichroism and Circular Dichroism
2010This book provides an introduction to optical anisotropy (linear dichroism, LD) and optical activity (circular dichroism, CD) as techniques for the study of structures and interactions of molecules in solution. The book covers the use of these techniques for both small and large molecular systems with particular emphasis being placed on proteins and ...

Circular Dichroism and Linear Dichroism
1997Abstract This book provides an introduction to all those who wish to use the complementary spectroscopic techniques of optical activity (circular dichroism, CD) and optical anisotropy (linear dichroism, LD) for the study of the structure of molecules and interactions between molecules in solution.

Magnetic Circular Dichroism Spectroscopy
2011Being able to probe the structure and energy levels of metal ions in biological systems is an important goal of bioinorganic scientists. Several of the techniques used rely on the paramagnetic property of certain oxidation states of metal ions. MCD spectroscopy is one of those techniques and represents an effective way of obtaining structure/electronic

Annual Review of Physical Chemistry, 1974
Magnetic optical activity (MOA) is induced in all matter by a longitudinal magnetic field. Magnetic optical rotation (MOR, the Faraday effect) and mag netic circular dichroism (MCD) arise respectively from the difference in refrac tive indices and absorption coefficients of left and right circularly polarized (CP) light due to the applied magnetic ...
