Experimental (Exp) and theoretical (Calc) UV-vis absorption spectra of a test sample “CAB_15_15” prepared with chlorophyll a (15 ppm) and chlorophyll b (15 ppm) diluted in a refined oil. Wavelengths are reported in nm. The optical length was of 0.5 cm. Single pigments’ spectral contributions obtained from the deconvolution analysis are also reported, namely chlorophyll a and chlorophyll b. The spectral base-line due to the oil matrix is reported as ‘triolein’ spectral contribution.
