Unusually high spin–orbit coupling in the methionine singlet–triplet transition and the role of magnetic perturbations in amino acids

Year: 2025

Type: article

Abstract: band is quite high for methionine and cysteine. The results demonstrate that the presence of sulfur in amino acids enhances the SOC effect, increasing the intensity of the singlet-triplet absorptions up to a measurable extinction coefficient. The importance of these SOC effects on the photochemical properties of proteins is emphasized together with the potential role of triplet-singlet transitions in photobiology.
