The goal of
this note is to illustrate how molecular structure is extracted from a spectrum.
Topics covered includes: Atoms, Diatomic Molecules , All Tricks In Molecular
Structure Theory, Born-oppenheimer, Transition Intensities For Diatomics,
Electronic Structure Models, Polyatomic Molecules.
Recent evolutions in nanosciences and
nanotechnologies provide strong arguments to support the opportunity and
importance of the topics approached in this book, the fundamental and
applicative aspects related to molecular interactions being of large interest in
both research and innovative environments. We expect this book to have a strong
impact at various education and research training levels, for young and
experienced researchers from both academia and industry.
lecture notes have been prepared to give an introduction into the foundations of
atomic and molecular physics with an emphasis on the interaction of these atomic systems
with light, and in more general, with electromagnetic fields. Topics covered
includes: Wave-corpuscular duality of photons and massive particles, Angular
momentum in quantum mechanics, Atomic spectra, simple models of atoms, Spin and
the fine structure, Many-body problems, systems of identical particles,
Molecular structure and spectra, Bose Einstein Condensation, Elements of
coherent atom field interactions, Atoms in Strong Fields, Photons, A quantum
paradox and the experiments.
This note covers the following topics: Molecular Shapes, What
Determines the Shape of a Molecule, Valence Shell Electron Pair, Repulsion
Theory, Molecular Arrangments, Lone pairs and Bond Angle, Multiple Bonds and
Bond Angles, Trigonal Bipyramidal arrangment, Polarity, Overlap and Bonding,
Hybrid Orbitals, Valence Bond Theory, Single Bonds, Multiple Bonds, Delocalized
Electrons, Orbitals in Molecules.

This book is an introduction to molecular electronic structural
theory. It is aimed at students who have reasonable familiarity with
differential and integral calculus and are beginning a study of the physical
description of chemical systems.
