circular dichroism in a sentence

Examples

1. Alternative techniques are Optical rotatory dispersion, vibrational circular dichroism and the use of chiral shift reagents in proton NMR and Coulomb Explosion Imaging.
2. Evidence for the helix structure in the crystalline state is derived from X-ray crystallography and from NMR spectroscopy and circular dichroism in solution.
3. His scientific work involved the characterization of biopolymers such as DNA, proteins and collagen by optical methods such as circular dichroism and light scattering.
4. However, the majority of studies have demonstrated that BSP has no ?-helical or ?-sheet structure by 1D NMR and circular dichroism.
5. For instance, choosing right and left circular polarizations as basis functions simplifies the solution of problems involving circular birefringence ( optical activity ) or circular dichroism.
6. Circular dichroism ( CD ) is then defined as ?k = k   k +, and it follows the sign convention of natural optical activity.
7. Cuvettes to be used in circular dichroism experiments should never be mechanically stressed, as the stress will induce birefringence in the quartz and affect the measurements made.
8. Proteins in the native state will have defined secondary structure, which can be detected spectroscopically, by circular dichroism and by nuclear magnetic resonance ( NMR ).
9. X-ray diffraction is still considered the ultimate proof of absolute structure, but other techniques such as circular dichroism spectroscopy are often used as faster alternatives.
10. Contrast due to polarization is invaluable in distinguishing fluorescence and diffraction signals and imaging magnetic domain structure by using techniques such as linear and circular dichroism and magnetic diffraction.
