Real-time measurement of molecular orientation using linear polarized light
In the optical waveguide spectroscopy, linearly polarized light can be used as the incident light. The longitudinal wave is used for P (TM) polarized light and the transverse wave for S (TE) polarized light, and the spectra are measured. And then the molecular orientation can be known from the absorption intensity ratio of each spectrum. (Fig.8,9,10)
