This course presents an introduction to quantum mechanics. It begins with an examination of the historical development of quantum theory, properties of particles and waves, wave mechanics and applications to simple systems — the particle in a box, the harmonic oscillator, the rigid rotor and the hydrogen atom. The lectures continue with a discussion of atomic structure and the Periodic Table. The final lectures cover applications to chemical bonding including valence bond and molecular orbital...

What is a photomultiplier? - A vacuum tube consisting of a photoemissive cathode, a series of intermediate electrodes called dynodes, and a collection anode. What does a single-beam spectrophotometer do? - A single-beam spectrophotometer employs one beam of radiation that irradiates one cell. What happens in a deuterium lamp? - The lamp energy from the power source produces an excited deuterium molecule that dissociates into two atoms in the ground state and a photon and the energies of th...
