Fluorescence scattering experimental work

Figure 4.1. Time scales for rotational motions of long DNAs that contribute to the relaxation of the optical anisotropy r(t). Experimental methods used to study these motions in different time ranges are also indicated along with the authors and dates of some early work in each case. FPA, Fluorescence polarization anisotropy (Refs. 15, 18-20, and 87) TPD, transient photodichroism (Refs. 28 and 62) TEB, transient electric birefringence (Refs. 26 and 27) DDLS, depolarized dynamic light scattering (Ref. 116) TED, transient electric dichroism (Refs. 25, 115, and 130) Microscopy, time-resolved fluorescent microscopy (Ref. 176).

Mefliods of study and data interpretation still require further work and refinement. Several experimental techniques are used, including microscopy (TEM, SEM) dynamic light scattering " using laser sources, goniometers, and digital correlators spectroscopic methods (UV, CD, fluorescence) fractionation solubility and viscosity measurements and acid-base interaction.
