When 0 > e, i.e., within the region of total reflexion, p given by (4.1.39) becomes complex, showing that the medium is now circularly dichroic. The real part which represents the rotatory power is... 

Circular dichroic spectroscopy (CD) is a powerful method for determining the absolute configurations and confirmations of chiral molecules. In particular, the exciton-coupled circular dichroism arising from through-space chromophore chromophore interac tions, called exciton coupling, is one of the most... 

We now turn to relativistic effects in the spectroscopy of superconductors. Several recent experiments have reported the observation of dichroic phenomena in superconductors (Lawrence etal. 1992 Lihn< f al. 1996 Lyons et al. 1990,1991 Weber et al. 1990 Wu et al. 1996). On the theory side, the difference A P between the power absorption of left- and right-circularly-polarized light has been investigated on the... 

Figure 10 illustrates schematic drawing of objective-type TIRFM. A high numerical aperture objective lens is mounted on an inverted microscope. A laser beam is passed through a neutral density filter (ND) and a beam expander (BE) to adjust its power and diameter. When the laser polarized linearly is used, the polarization of the laser beam is converted from linear to circular by a quarter-wave plate (A/4). The laser beam is focused by a lens (L) on the back focal plane of the objective, so that specimens are illuminated uniformly with Koehler illumination. By shifting the position of the mirror (M) located between the lens (L) and dichroic mirror (DM), the path of the incident laser light is shifted from the center to the edge of the objective. At the center position, the microscope can be used as a standard epi-fluorescence microscope (Fig. 10b).
