| 11. | The term " optical activity " is derived from the interaction of chiral materials with polarized light.
|
| 12. | Here he continued research on metal coordination compounds and began his important work on optical activity of metal complexes.
|
| 13. | There, he invented fluorescence detected circular dichroism for measuring the optical activity of the fluorescent component of a solution.
|
| 14. | In electromagnetism, spatial dispersion plays a role in a few material effects such as optical activity and doppler broadening.
|
| 15. | The non-isotropic permittivity for nonzero wavevector leads to effects such as optical activity in solutions of chiral molecules.
|
| 16. | In order to display optical activity, a fluid must contain only one, or a preponderance of one, stereoisomer.
|
| 17. | In the presence of an applied magnetic field, it is possible for samples of all compounds to exhibit optical activity.
|
| 18. | The absence of optical activity is due to a mirror plane in the molecule, [ segmented line in picture below]
|
| 19. | With three carbon atoms, dihydroxyacetone is the simplest of all ketoses and is the only one having no optical activity.
|
| 20. | At the fundamental level, optical activity is a case of circular birefringence, and can best be understood in that way.
