Futurology

Although singlet oxygen also exists and is reasonably (meta)stable, as you probably know, but someone reading might not. It has some neat properties, and is used as a source of excitation in a lot of chemical lasers because of the ease of production.

Do you know of any good sources for learning why, theoretically, certain molecule configurations work and are stable? I have a pretty good grasp of the basic quantum mechanics of electrons to draw from.
