The electric structures of double-chain of hydroxy polyacene were studied by quantum chemistry crystal orbital CNDO/ 2 method, and considered the hydrogen-binding interaction of hydroxy-polyacene.
So, for example, in a hydrogen atom, if you take the binding energy, the negative of that is going to be how much energy you have to put in to ionize the hydrogen atom.
例如在氢原子里面,如果你取一个结合能,它的负数就是。

What is the binding energy of the ground state electron in hydrogen?
