The Shell Vectorial Model,By resorting to the principles of quantum mechanics and after having dealt with specific atoms, one can now proceed to the description of the electronic structure in generic multi-electron atoms. We shall see that the sequence of electron states accounts for the microscopic origin of the periodic Table of the elements.

Nuclear Moments and Hyperfine Interactions,Until now the nucleus has been often considered as a point charge with infinite mass, when compared to the electron mass.

Molecules: General Aspects,In this chapter we shall discuss the general aspects of the first state of “bonded matter”, the aggregation of a few atoms to form a molecule.

Electronic States in Diatomic Molecules,In this chapter we specialize the concepts given in Chap. . for the electronic states by introducing specific forms for the wavefunctions in diatomic molecules.

Nuclear Motions in Molecules and Related Properties,In the framework of the Born-Oppenheimer separation (Sect. .), once that the electronic state has been described and the eigenvalue . and wavefunction . have been found, then the motions of the nuclei are described by a function ., where . represents the quantum label for the electrons and . are the quantum numbers (to be found) for the nuclei.

Crystal Structures,In this Chapter and in the following three Chapters we shall be concerned with the general aspects of the solid state of the matter, namely the atomic arrangements where the interatomic interactions are strong enough to keep the atoms bound at well defined positions.
