Examination board not defined

Prerequisites: It is suggested to have passed the following examinations: Mathematics 2, General Physics 1 and 2, Quantum Physics.
Target skills and knowledge: Students will acquire the principles of Quantum Mechanics for the descritpion of molecules and of their properties. On this basis she/he will acquire the principles of optic and magnetic spectroscopies and those of statistical mechanics.
Examination methods: The examination will be based on a written and oral test.
Assessment criteria: Students have to show the ability of being able to use the priciples of Quantum Mechanics to describe molecular properties. Furthemore she/he will be able to apply these principles to the description of the interaction between electromagnetic fields and molecular systems and how the properties of molecules ensemble can be described statistically.
Course unit contents: Basis of Quantum Mechanics and of multielectron systems. Spin-orbit coupling and selection rules. Quantum mechanics of molecules. Born-Oppenheimer approximation. Valence bond theory for homonuclear and etheronuclear diatomic molecules and for polyatomic molecules. Hybrid orbitals. Molecular orbital theory for polyatomic molecules. Huckel approximation. Mean field molecular quantum calculations. Hartree-Fock approach. Semiempirical and ab-initio calculations. Configuration interaction as post Hartree-Fock approach. Density functional Theory.
Molecular symmetry. Point symmetry groups and classification of the molecular symmetries. Matrix representation of the molecular symmetry operations. Reducible and irreducible representations of the point groups. Characters and tables of characters. Reduction of reducible representations. Symmetry adapted linear combinations of functions with given symmetry. Symmetry of product of functions. Vanishing integrals. Symmetry classification of vibrational modes.
Spectroscopies. Time independent and dependent perturbation theory. Interaction with electromagnetic fields and transition dipole moments. Principles for absorption, emission and scattering tecniques. Fourier transform techniques. Absorption intensity and its relation to the transition dipole moment. Lambert Beer law. Einstein coefficients. Selection rules for transitions.
Rotational energetic levels and selection rules for rotational spectra.

Hyperfine structure of the EPR spectrum and its origin.
Introduction to Statistical thermodynamcis.Boltzman distribution. Molecular partition function. Molecular internal energy and entropy. The canonical partition function. Internal energy and entropy of a canonical ensemble. Other thermodynamic functions: Enthalpy, and Gibbs and Helmholtz free energies. Translational, rotational, vibrational and electronic contributions to the molecular partition function. Statistical Thermodynamics applications: equation of state and equilibrium constants.
Planned learning activities and teaching methods: Frontal lessons also for exercises. It will be given large possibilities to questions for a guided advancement of the arguments comprehension.
Additional notes about suggested reading: The suggested textbook also reports many solved exercises which are very important for understanding the subject. A parallel textbook reports all the complete solutions for all the exercises.
