Synchrotron linear dichroism spectroscopy and quantum chemical calculations Journal/Source: Chem. Phys., 352 (1-3), 167-174, (2008); https://doi.org/10.1016/j.chemphys.2008.06.007 Data: diagram, table Energy/Wavelength range: 196 - 600 nm Resolution: 0.5-1.0 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: in stretched poly(vinyl alcohol) pH: Comments: The electronic transitions of emodin (1,3,8-trihydroxy-6-methyl-9,10-anthraquinone, E) and its conjugate base (3-oxido-6-methyl-1,8-dihydroxy-9,10-anthraquinone, Ecb) were investigated by UV/Vis linear dichroism (LD) spectroscopy on molecular samples aligned in stretched poly(vinylalcohol).
