Oscillatory electrical birefringence

In this example (Mori et al., 1982), the experimental method is oscillatory electric birefringence (Morris and Lodge, 1986), in which... 

In addition to the substantial literature on solvent and small-molecule translational diffusion, there is also a significant literature on small-molecule rotational diffusion. Experimental methods that report rotational diffusion behavior include VH tight scattering, as examined in different time domains with Fabry-Perot interferometry and photon correlation methods, nuclear magnetic resonance, oscillatory electrical birefringence, and time-resolved optical spectroscopy. 

An alternative physical probe of solvent motion is oscillatory electrical birefringence (OEB), as applied to Aroclor 1248 solutions of polystyrene and polybutadiene by Morris, et a/. (43). In these systems, OEB gives a solvent relaxation time that depends on temperature and polymer concentration. Measurements of r at the...
