b At higher chromophore concentrations the relationship between absorption and chromophore concentration becomes nonlinear. This is attributed to a shadow effect, whereby one molecule in a photon’s path casts a shadow on another molecule directly behind it. This leads to underestimation of chromophore concentration, but does not in itself alter the fate of a chromophore after excitation takes place.
