Quantum Chemistry

Quantum chemistry is the application of quantum mechanics to chemical problems. With Wolfram|Alpha, one can investigate the connection between observed chemical properties and the underlying quantum mechanical nature of atoms and molecules. Explore properties such as electronic configurations, orbital diagrams, term symbols and emission spectra.
