Multiconfigurational quantum chemistry for ground and excited states

Multiconfigurational Quantum Chemistry

The concept of inactive and active orbitals is introduced and the complete active space wave function is defined. They have used these characters to construct the multiconfigurational wave functions required for chemical reactions. Illustrative results are presented for the main group atoms spin—orbit splittings , the electronic spectrum of the iridium atom, the ground state of Tl 2 and Pb 2, and for the electronic spectrum of PbO. Accessible to any reader with a background in quantum mechanics and quantum chemistry, the book contains illustrative examples showing how these methods can be used in various areas of chemistry, such as chemical reactions in ground and excited states, transition metal and other heavy element systems. He is a former board member of the Swedish National Research Foundation, a member of the Swedish Royal Academy of Sciences, the Nobel Committee for Chemistry, the International Academy of Quantum Molecular Sciences, and is on the advisory editorial board for Chemical Physics Letter, Molecular Physics, International Journal of Quantum Chemistry, and Chemical Physics Physical Chemistry.

The first book to aid in the understanding of multiconfigurational quantum chemistry, Multiconfigurational Quantum Chemistry demystifies a subject that has historically been considered difficult to learn. A multiconfigurational approach to the quantum chemistry of heavy element compounds is described. Relativistic effects are treated in two steps, both based on the Douglas—Kroll Hamiltonian. Without attempting to be complete, it has been illustrated that how this choice can be made for some typical electron structure problems. Go to our for details.
