The Absorbance and Fluorescence of Chlorophyll-b in Organic Solvents ()

[摘要] The wavelength of chlorophyll-b on the absorbance and fluorescence emission were shifted to the longer depending on the increasing of solvent polarities but fluorescence excitation spectra were not. The presence of chl-b oligomers and monomers were identified by the specra of fluorescence emission. Fluorescence excitation, absorbance and the measurement of its intensities vs. the concentration of n-prOH added to chl-b solution. The calibration curve of chl-b solution were not obeyed to Beer's law in the range of concentrated soln. because of the presence as the oligomers.
