Polarisation properties

An important wavelength describing the distribution is the characteristic (critical) wavelength, Xc, given by 

In the plane of the orbit, the emitted SR is 100% linearly polarised with the electromagnetic E vector parallel to the electron acceleration. This is as one would expect if we simply visualised the orbit edge-on as a dipole source. Away from the plane of the orbit there is a significant perpendicular component. 

In figure 4.5 we see a plot of the parallel and perpendicular components of polarisation as a function of ip (expressed in multiples of the

The activity coefficient at infinite dilution of a solute y°° is related to the relative strength of an intermolecular interaction with the ionic liquid. The choice of the model solutes was based on their Abbout-Kamlet-Taft parameters [4, 75, 76], to exhibit prevailing forces with regard to the hydrogen bond acceptor, donor and polarisability properties. Similar probe molecules have been used in computational studies [62, 63],... 

Ferroelectric Perovskites and Polarisation Properties. Cubic Phase. 

Consequently, the Raman scattered light emanating from even a random sample is polarised to a greater or lesser extent. For randomly oriented systems, the polarisation properties are determined by the two tensor invariants of the polarisation tensor, i.e., the trace and the anisotropy. The depolarisation ratio is always less than or equal to 3/4. For a specific scattering geometry, this polarisation is dependent upon the symmetry of the molecular vibration giving rise to the line. 

Exploring orientation properties in polymers films often requires a high spatial resolution and a high degree of polarisation of the probing beam. Synchrotron radiation has well known polarisation properties the emission follows strict polarisation properties, as detailed in [21].
