Born-oppenheimer bo approximation
WebNow here is the technical BO approximation:: ... The Born-Oppenheimer approximation comprises two different approximations: Adiabatic separation of electron and nuclear coordinates. Semi-classical approximation for nuclei. Previous answers have already addressed (1). I would also like to add that although it neglects electron-phonon coupling ... WebThe Born-Oppenheimer (BO) approximation is ubiquitous in quantum chemical calculations of molecular wavefunctions. It consists of two steps. In the first step the nuclear kinetic energy is neglected, [1] that is, the corresponding operator Tn is subtracted from the total molecular Hamiltonian. In the remaining electronic Hamiltonian He the ...
