Physical Chemistry I

The failures of classical physics. The principles of quantum mechanics. Quantum mechanical description of simple systems: free particle, particle in a box (one and two dimensions), rotational motions (two and three dimensions). The hydrogen atom and the structures of many electron atoms. The electronic molecular description of molecules: the Molecular Orbital and the Valence Bond approaches. An introduction to spectroscopy: the time dependent Schrödinger equation. Rotational spectroscopy of biatomic molecules. Vibrational and vibro-rotational spectroscopy of biatomic molecules. The vibrations of polyatomic molecules.
