WebHypsoporphyrins exhibit blue-shifted Soret and Q bands, while hyperporphyrins exhibit extra bands relative to normal porphyrins at wavelengths above 300 nm. Unlike normal spectra, which are dominated by porphyrin π → π* transitions, hyper spectra also involve additional types of transitions, notably charge transfer (CT) transitions. WebIn the absorption spectrum of porphyrins, the intense soret band is attributed to the S0 to S2 transition whereas the q bands are attributed to the S0 to S1 transition.
