Migration of Electronic Energy from Chlorophyll b to Chlorophyll a in Solutions
Biophysical Journal, 1972 Absorption, emission, and fluorescence excitation spectra of pure solutions of chlorophyll a (Chl a) and chlorophyll b (Chl b) in diethyl ether and of equimolecular mixed solutions of the two pigments, were determined at room temperature as functions of concentration (in the range from 5 x 10(-6) M to 4 x 10(-3) M) and of wavelength of the exciting ...

Deriving sun-induced chlorophyll fluorescence from airborne based spectrometer data [PDF]
, 2010 Sun-induced chlorophyll fluorescence (Fs) is a promising parameter for remote measuring plant photosynthesis. It has been demonstrated that Fs at cell and leaf level is strongly related to photosynthesis.

Talanta, 1992 The enhancement of the fluorescence of chlorophyll a and chlorophyll b in a non-ionic micellar media is used for the establishment of a new analytical method for the determination of these pigments. After optimization of the variables, including concentration of surfactant, pH, temperature and percentage of organic solvent, the analytical figures of ...
