# Quantum Mechanics Topics

**1.054571596e-34 J s**- Dirac′s constant, also known as h bar.
**4.13566727e-15 eV s**- Plancks Constant.
**6.58211889e-16 eV s**- Known as h bar or Dirac′s constant.
**6.626e-34 Js**- Planck′s constant.
**Atomic Unit**- A system of non-SI units used in quantum chemistry to simplify calculations and mathematical expressions.
**Bose-Einstein Statistics**- Quantum statistics for particles not obeying the exclusion principle.
**Exclusion Principle**- No two electrons can have the same set of quantum numbers. This statement also applies to protons, neutrons, and other baryons.
**Pauli Exclusion Principle**- No two electrons can have the same set of quantum numbers.
**Quantum Chromodynamics**- The quantum theory of the strong interaction.
**Quantum Electrodynamics**- The quantum theory of the electromagnetic interaction.

**Schrodinger Equation**- The basic equation of quantum mechanics.
**Schrödinger, Erwin**- Austrian physicist; developed atomic theory of wave mechanics.
**State**- Solution to Schroedinger equation defined by a unique set of quantum numbers.
**Wave Particle Duality**- The observation that electrons; photons; and other very small entities behave like particles in some experiments and like waves in others.
**Wavefunction**- A mathematical function that gives the amplitude of a wave as a function of position.
**Zero Point Energy**- A minimum possible energy for an atom or molecule predicted by quantum mechanics.
