The Born-Oppenheimer Approximation
where R is the set of nuclear coordinates and r is the set of electronic coordinates. If spin-orbit effects are important, they can be added through a spin-orbit operator Ĥso. Unfortunately, the V̂eN(r,R) term prevents us from separating Ĥ into nuclear and electronic parts, which would allow us to write the molecular wavefunction as a product of nuclear and electronic terms, Ψ(r,R) = Ψ(r)χ(R). W...
متن کاملTolman–Oppenheimer–Volkoff (TOV) Stars
We present a set of lecture notes for modeling stellar structure in regimes where general relativistic effects become important, such as for neutron stars. The framework draws directly from solving the Einstein equation for a spherically symmetric star in static equilibrium in terms of energy density, pressure, and a term like the gravitational potential. The equation is presented as a somewhat...
متن کاملJane Marion Oppenheimer (1911-1966)
Jane Marion Oppenheimer [5], embryologist and historian of science and medicine, was born on 19 September 1911 in Philadelphia, Pennsylvania, to Sylvia Stern and James H. Oppenheimer. After studying zoology at Bryn Mawr College [6], Oppenheimer received her AB degree in 1932. Oppenheimer received her PhD in embryology [7] at Yale University [8] in 1935 and worked as a research fellow from 1935?...
متن کاملNon-Born-Oppenheimer molecular dynamics.
Electronically nonadiabatic or non-Born-Oppenheimer (non-BO) chemical processes (photodissociation, charge-transfer, etc.) involve a nonradiative change in the electronic state of the system. Molecular dynamics simulations typically treat nuclei as moving classically on a single adiabatic potential energy surface, and these techniques are not immediately generalizable to non-BO systems due to t...
متن کاملNorth - Holland BORN - OPPENHEIMER REVISITED
The Born-Oppenheimer approximation [1] can be used whenever the hamilto..ian of a fast system depends on the coordinates of a slow system . In some textbooks, the problem is solved by freezing the coordinates of the slow system and solving the hamiltonian of the fast system; then the energy of the fast system enters the effective hamiltonian for the slow system as a potential energy term. This ...
