Symmetry,e, if we twirl the methane molecule by 120° about a C-H bond, it looks the same. It is often possible to derive, from the symmetry of the molecule, information about its quantum-mechanical properties, and this is the subject of this chapter.

Foam-Cells

Time Dependence, we return to a topic mentioned at the very beginning of the book, when we discussed how spectroscopy, through Bohr’s postulates, led to recognition that quantum-mechanical systems can exist only in states with certain energies. Our aim now is to derive Bohr’s rules.

He may take several more chemistry courses as an undergraduate and then seek a position in industry, or perhaps he will do graduate work in organic or inorganic chemistry. (Of course, one never stops hoping that, as a result of this first course, he will decide to l
