Electron attraction and chemical bonding

In recent years, electron attraction, real or apparent, has been studied in various areas of science and technology. By simulating the dynamical behav ior of the molecules H-2, Li-2(7), B-2(11), Ca-2(12), N-2(14), (O2H)-H-16, Li7H, CH4, and H2O in their ground states, and H-2 in its first excited sta te, we Show that the inclusion of electron attraction in the simulation yie lds, in all cases, correct bond lengths, correct vibrational frequencies, a nd, where significant, correct bond angles, whereas excluding electron attr action never does.
