Gauche effect definition

Wolfe23 defines the gauche effect as the tendency of molecules to adopt a structure maximizing the number of gauche interactions between adjacent lone pairs and/or polar bonds. Heteroatoms are assumed to be sp3 hybridized, thus having equivalent lone pairs (22). This phenomenological definition is unsatisfactory because it groups three different situations under the same title. [Pg.220]

The correlation functions relevant for spectroscopic observables have been computed, and compared with correlation functions for the decay of trans and gauche populations of specific bonds, whose time integrals lead quite naturally to the definition of effective kinetic rates. [Pg.213]
