Unlike fluorescence intensity which focuses on the quantification of emission intensity at a specific wavelength and neglects its polarization, fluorescence polarization specifically analyses as output the emission intensity of different .Fluorescence anisotropy or fluorescence polarization is a measurement of the changing orientation of a molecule in space, with respect to the time between the absorption and emission events. Search English. Corporate Global. Products Raman Imaging and Spectrometers Raman Research Solutions .
In a polarimeter (figure 2), plane-polarized light is introduced to a tube (typically 10 cm in length, figure 3) containing a solution with the substance to be measured. If the substance is optical inactive, the plane of the polarized light will not change in orientation and the observer will read an angle of [α]= 0 o. If the compound in the .A summary receiver operating characteristic curve was constructed. The area under the curve was 0.865.
