Time Dependence

  • J. Goodisman


So far, we have discussed the states of atoms and molecules, with no mention of processes that may change these states. We have showed how energies and other properties of the time-independent states of atoms and molecules may be calculated. Now, we discuss change or time dependence. This means that 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.
