This lecture is devoted to discussion of the wonderful Quantum world. Classical Mechanics, in spite of all of its impressive predictive power, fails to explain many microscopic behaviors. This led to the development of Quantum Mechanics, where electrons orbit nuclei in discrete energy levels, light can behave as a particle, and particles behave as waves. The location of microscopic particles can only be expressed in terms of probabilities....more

Professor Sylvia Ceyer focuses on the hydrogen atom, beginning with a discussion of electron binding energy to the nucleus. Other topics covered are verification of energy levels for the H atom (including photon emission, transitions between states, and photon emission) as well as the wavefunctions for an H atom. The stations state wavefunction is explained and the three quantum numbers used to describe a wave in 3D – principle quantum ...more

After pointing out several discrepancies between electron difference density results and Lewis bonding theory, the course proceeds to quantum mechanics in search of a fundamental understanding of chemical bonding. The wave function ψ, which beginning students find confusing, was equally confusing to the physicists who created quantum mechanics. The Schrödinger equation reckons kinetic energy through the shape of ψ. When ψ curves toward zer...more
