Abstract
The exciton model has been successful in interpreting the long-wavelength chiroptic properties of both quasi-infinite [1–6] polypeptides and of shorter oligopeptides [7–12]. Initially, only the electric dipole-electric dipole interaction (μ-μ mechanism) of the amide π-π* transitions was considered. After the discovery in the early 1960’s of a n-π* band at longer wavelength than the π-π* bands [13–17], several investigations were then undertaken to include magnetic dipole allowed transitions in the exciton scheme (local n-π interaction and nonlocal electric dipole-electric quadrupole interation; μi-mi and μi-mj mechanisms) [7–12].
