Polarization linearly polarized light

As the incident plane-polarized (linearly-polarized) light may be described as the superposition of two circularly polarized components of identical amplitude oscillating in phase, optical rotation was ascribed to the difference in the indices of refraction for left- (ml) and right-CPL ( r) in a chiral (optically active) medium, known as circular birefringence. Therefore, if LPL traverses a medium showing circular birefringence, the circularly polarized components slow to a different extent, and as a result, the plane of polarization is rotated with respect to the original polarization plane. Thus, optical rotation may be described as ... 

An interesting aspect of two-photon spectroscopy is that some polarization infonnation is obtainable even for randomly oriented molecules in solution by studymg the effect of the relative polarization of die two photons. This is readily done by comparing linearly and circularly polarized light. Transitions to A states will absorb linearly polarized light more strongly than circularly polarized light. The reverse is true of transitions to B ... 

Similar reasoning shows that were one to view along tiieX, Yand Z axes and polarization analyse the signal each time, whether excited by linearly or by naturally polarized light, the total intensity should be given by + 2/. Given eauation (Bl.3.23). if we add its denominator to twice the numerator we find that A...

In analogy with the depolarization ratio for linearly polarized light, the ratio of the two above quantities is known as the reversal coefficient, R(Q, given by... 

Figure 2 Projection of the time-dependent 6-field vector of light in the plene transverse to the direction of propagation for linearly polarized light (a), as for incident p-light in MOKE, and rotated and alliptically polarized light (b), which is the general case for light reflected from a Karr-active surface.

The principal of measurement is shown schematically in Fig. 4.61. Linear polarized light is reflected from a sample surface which must be flat and sufficiently reflecting. The state of polarization of the incident light is changed, by reflection, into ellipti-...

A depolarization measurement consists of exciting a fluorescent sample with linearly polarized light and measuring the polarization of emitted light at right angles to the plane of excitation. The polarization of the emitted light is defined as...

From the condition Eq. (5) it is readily seen that for linearly polarized light the P term vanishes from Eq. (4) and the more familiar form of Eq. (2) is recovered for linear polarization. Evidently, for linear polarization is just equivalent to the...
