dichroism

(ˈdaɪkrəʊˌɪzəm)
n
1. (General Physics) Also called: dichromaticism a property of a uniaxial crystal, such as tourmaline, of showing a perceptible difference in colour when viewed along two different axes in transmitted white light. See also pleochroism
2. (Chemistry) a property of certain solutions as a result of which the wavelength (colour) of the light transmitted depends on the concentration of the solution and the length of the path of the light within the solution

Circular dichroism spectroscopy reveals invariant conformation of guanine runs in DNA.
As spectroscopic techniques, UV-visible, fluorescence spectroscopy, and circular dichroism (CD) techniques have been chosen.
The circular dichroism spectra (CD spectra) were measured by using J-810 circular dichroism spectrum (Shimadzu, Japan), the range of emission wavelength were from 200 nm to 300 nm, the scanning speed was 100nm*[min.sup.-1], the response time was 1 second, and its bandwidth was 1.71 nm.

An imaginary part of k involves a difference in absorption between both waves, so a linearly polarized plane wave will become elliptical and, eventually, circular ("circular dichroism").
Circular dichroism spectroscopy (CD) and polyacrylamide gel electrophoresis (PAGE) were used to observe the effect of base substitution (s) on the formation, thermal stability, and conformation of G-quadruplexes.

Since the mirror symmetry of unit-cell is broken either in the perpendicular plane or in the propagation direction, numerous outstanding electromagnetic (EM) properties of the CMMs can be achieved, such as negative refraction [3-8], giant optical activity [6, 7, 9] and circular dichroism [8,10], asymmetric transmission (AT) effect [11-15], and polarization conversion or rotation [16-19].
By means of yeast two hybrid, isothermal titration calorimetry, circular dichroism, confocal microscopy and pull-down assays we have demonstrated the interaction between Claudin-3 and the PDZ domain of nNOS and proposed tyrosine phosphorylation as a binding regulation mechanism.

Unfortunately, direct evidence for intrinsic ferromagnetism in this material remains elusive, but nowadays powerful element and site-specific probes such as X-Ray Magnetic Circular Dichroism (XMCD) and X-Ray Absorption Spectroscopy (XAS) are proving invaluable.
