    Schrodinger equation as a theoretical start point should be able to explain all the phenomena happened in the world of atom and molecule. However, due to the potential energy of a many-body system is usually too complicate to obtain, the exact analysis for a molecular system with many constituent atoms also becomes very difficult to obtain. It is a pity that we have an exact analytical theory but can hardly apply it to the all the cases of molecules only for the reason that we get stuck to the mathematical problems.
