Molecular Electronic-Structure Theory Trygve Helgaker, Poul Jorgensen, Jeppe Olsen
Publisher: Wiley

Two types of devices are considered here: (a) Molecular electronic devices: In the first part of this work, we use the multi-particle Hilbert (Fock) space of the exact diagonalized many-electron Hamiltonian of various molecular structures. Using a kinetic equation in We develop a generic mechanism for multiple NDRs to occur due to "spin blockade" and develop a theory for hysteretic bistability that is induced via feedback from hyperfine scattering of electron spins with the nuclear spins. I came into the field in the 1970s when it was just becoming possible to do useful calculations on molecules. Computational investigations of molecular electronic structure using ab initio and density functional molecular orbital techniques.

Molecular Electronic-Structure Theory makes extensive use of numerical examples,. However, because the four nucleotides are very similar in their chemical structures, they cannot easily be distinguished using this technique. Our research typically involves close collaboration with CCB experimentalists. Introduction to Quantum Theory and Atomic Structure - P. Theoretical and Computational Chemistry #11: Relativistic. Fundamentals of Quantum Chemistry Molecular Spectroscopy and Modern Electronic Structure Computations - Michael Mueller. As a starting point for such experiments, one needs a very good knowledge of the electronic structure, energetics and long-range behavior of these molecular ions. We perform accurate ab initio and electric quadrupoles. We believe, this work would lay foundation, not only for new experiments in ultracold physics and chemistry, but would also provide valuable starting point for theoretical calculations involving low temperature scattering and resonant charge transfer. Tensor Structure of the Many-Electron Hamiltonian and.
