We argue that the mixing between the Q and B bands should have a magnified importance in the porphyrin aggregates having an excitonic structure with a collective superstate. A quantitative account of the excitonic intensity borrowing in such systems will be discussed. A remarkably simple explanation of the enhancement of hyperchromism will be given and illustrated for the porphyrin J-/H- and cylindrical aggregates.
