In chemistry, pi stacking (also called π–π stacking) refers to the presumptive attractive, noncovalent pi interactions (orbital overlap) between the pi bonds of aromatic rings. However this is a misleading description of the phenomena since direct stacking of aromatic rings (the "sandwich interaction") is electrostatically repulsive. What is more commonly observed (see figure to the right) is either … NettetRecently, there is mounting evidence that non-covalent interactions involving aromatic rings are also potent forces for the recognition between small drug-like compounds … gripper that steve ramsey recommends
