ABSTRACT The benzamide chromophore is widely used as a Cottono- genic derivative of primary amines for stereochemical studies by circular dichroism. The assignments based on the exciton chirality method are reliable since the benzamide group has well-defined geometry and con- formation.   ABSTRACT The benzamide chromophore is widely used as a Cottono- genic derivative of primary amines for stereochemical studies by circular dichroism.
