The transition dipole coupling model allows to vary systematically many parameters, such as chromophore geometries and transition dipoles. We used it to explore conditions favorable to chirality enhancement observed in many experiments on protein amyloidal precipitates. Stacking of β-sheet planes has been identified as a particularly powerful mechanism of the enhancement.
