Thus, the correlation between biological activity and steric 0electrostatic potentials was much better than the correlation with only the position of the three binding sites. borchie auto 15Steric effects arise from the spatial arrangement of atoms. When atoms come close together there is generally a rise in the energy of the molecule. Steric effects are nonbonding interactions that influence the shape (conformation) and reactivity of ions and molecules. Steric effects complement electronic effects, which dictate the shape and reactivity of molecules. Steric repulsive forces bet… borchie cerchi audi
