Chemistry without the Born–Oppenheimer approximation
In quantum chemistry and molecular physics, the Born–Oppenheimer (BO) approximation is the best-known mathematical approximation in molecular dynamics. Specifically, it is the assumption that the wave functions of atomic nuclei and electrons in a molecule can be treated separately, based on … See more The benzene molecule consists of 12 nuclei and 42 electrons. The Schrödinger equation, which must be solved to obtain the energy levels and wavefunction of this molecule, is a partial differential eigenvalue equation in … See more It will be discussed how the BO approximation may be derived and under which conditions it is applicable. At the same time we will show how the BO approximation may … See more Resources related to the Born–Oppenheimer approximation: • The original article (in German) • Translation by S. M.
