Among the methods avallable for the analysis of structures of drug—DNA complexes in solution, the electric dichrolsin is particularly simple, does not require much material, and provtdes information, which cannot be obtained as conveniently by other methods The principle of the electric dichroism is straightforward: electric field pulses are used to align DNA molecules in . The absorption changes due to the dichroism can be deduced from the transient recorded when the electric pulse is applied to the sample. The measurement of the dynamic behaviour and linear electric dichroism of a thin layer of the guest–host system (Sudan black B dye-E8) was performed with the following apparatus ().A Spectra physics He/Ne laser (Scientific and Cook, .

We develop a general theory of birefringence and dichroism to account for the optical (and electrical) anisotropy exhibited by the refractive indices and attenuation coefficients of biological tissues or of composites of aligned particles. The primary bases for dichroism are the same as we considered before for birefringence (i.e., anisotropic parameters of the particles and of the .
Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light. Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible spin angular momentum states for a photon, and so circular dichroism is also referred to as dichroism for spin angular momentum.

Coherent electric waves have been predicted to exist in biological systems. (1) We try to link the consequences of their propagation in the cell medium to some peculiar features of cell architecture and organization such as cytoskeleton formation and dynamics.

Electric birefringence (EB) of suspensions of anisotropic particles can be considered an electrokinetic phenomenon in a wide sense, as both liquid motions and polarization of the electrical double. A novel method has been developed for the rapid and simultaneous measurement of linear electric birefringence and linear electric dichroism of homogeneous, optically absorbing materials using pulsed electric fields. This method has been used to measure the linear electric birefringence and the linear electric dichrAuthor: A. J. Amass, M. S. Beevers, T. R. Farren. Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive).The birefringence is often quantified as the maximum difference between refractive indices exhibited by the material. The magnetically induced circular birefringence and dichroism of several bands in the electronic spectrum of ICl have been studed with a resolution of Cited by:
