Quantum Chemistry and Spectroscopy - Quantum Chemistry 4.2 - Postulates of Quantum Mechanics 2: Operators

Short lecture on postulate 2 of quantum mechanics. A postulate is a statement that is not proven, but assumed to be true and judged on the validity of its conclusions. Postulate 2 of quantum mechanics states that for every classical observable (physical property), there corresponds a linear, Hermitian, quantum mechanical operator. The definition of linear operators is explained here, whereas Hermitian operators are discussed later in video 4.7. Common operators include those for total energy (Hamiltonian), potential energy, kinetic energy, position, and momentum.
