Here we have the molecular orbital energy diagram for this chlorophyll molecule. Matchthe absorption peaks labeled in Figure 4.7 above with the transitions shown in themolecular orbital energy diagram.LUMO+1LUMOHOMOНОМО-1

Higher the wavelength shorter will be the energy gap between the two energy levels
