El propósito del presente trabajo será poner de manifiesto que la química cuántica es una disciplina basada primariamente en modelos, y no en teorías que establecen un marco conceptual específico y autónomo. Esta característica ...

In this thesis we study mass-imbalanced three-body system in two dimensions using BornOppenheimer approximation. Considering the heavy-light particle system interacting through zero-range interaction and disregarding ...

We analyse a nonadiabatic self-consistent field method by means of an exactly-solvable model. The method is based on nuclear and electronic orbitals that are functions of the cartesian coordinates in the laboratory-fixed ...

In this work, we present a quantum mechanical treatment of the three-body (Formula presented.) molecular system in the Born–Oppenheimer (BO) approximation, were the nuclei dynamics is evaluated over the potential energy ...

The Born-Oppenheimer approximation is the standard method for the studying atoms and molecules. It is founded on the observation that the energy scale of the electron dynamics in a molecule is larger than that of the nuclei. ...
