- W2583521948 abstract "Linear dichroism provides information on the orientation of chromophores that are components of, or bound to, an orientable macromolecular, such as DNA. For molecular alignment induced by laminar hydrodynamic shear, the two principal axes orthogonal to the direction of alignment are not equivalent. As a result, the magnitude of the increase or decrease in the flow induced change in absorption for light polarized parallel to the direction of flow can be more than a factor of two greater than the corresponding decrease or increase for light polarized perpendicular to the plane defined by the directions of the flow and the direction of the flow velocity gradient. The ratio of the two flow-induced changes in absorption give the dichroic increment ratio. This ratio is characterized using the equivalent orthogonal orientation model that assumes that each absorbing unit is aligned parallel to one of the principal axes of the apparatus. The absorption of the aligned molecules is characterized by components parallel and perpendicular to the orientable axis of the molecule. Although determined by measurements of polarized absorption, the dichroic increment ratio is independent of the optical properties of the aligned molecules, and therefore independent of wavelength. The dichroic increment ratio can be used to determine if the alignment is effectively uniaxial and, if not, the extent to which alignment of molecules parallel to the flow gradient is decreased relative to alignment in the direction perpendicular to both the direction of flow and the flow gradient. Analysis of published data indicates that for the alignment of DNA in rectangular flow cells, where the average shear tends to be low, there are significant differences between these alignment probabilities, but for the higher average shear produced in a Couette cell, the alignment can be essentially uniaxial. The equivalent orthogonal orientation model returns results equivalent to those of more general tensor models provided that only optical properties for light propagation and polarizations parallel to principal axes of the experimental system are measured, which is the usual configuration of an linear dichroism experiment. Approaches for measuring the dichroic increment ratio with modern dichrometers are discussed." @default.
