- Nobelprize.org has a great online resource called The Quantised World (you'll recognize some of the figures from the lecture book).
- Tutorials: Electromagnetic Radiation | Light Emission and Absorption | Bohr Model | De Broglie Wavelength | Quantum Numbers | Electron Configuration
- an excellent, if somewhat long, tutorial from Physics2000, on the Quantum Atom. It goes on to Beyond the Hydrogen Atom.
- Check out the Orbitron, a gallery of atomic orbitals and molecular orbitals.
