The Soret band arises primarily due to an electron dipole movement that allows π-π* transitions; most common in porphyrin compounds. Most analytical studies of porphyrin‑containing moiety can be done using ultraviolet–visible spectroscopy and exciting wavelength at the respective Soret band wavelength. For example, the "Soret peak" is used to describe the absorption of vividly-pigmented heme-containing moieties, such as various cytochromes.
