The course contains elementary quantum mechanical models to: 1) extend the chemical bonding theory from KJEM110 (and KJEM120) and: 2) provide a basic understanding of a selection of important spectroscopic methods like for instance UV/Vis and IR. The course also comprises elementary statistical mechanics (for instance the Boltzmann distribution) to provide a basic molecular understanding of physical and thermodynamical concepts that are introduced in KJEM110. Specific examples will be shown of how molecular properties, by means of simple quantum mechanical models and spectroscopic data, via statistical mechanics can explain and systematize macroscopic thermodynamical properties. These include for instance chemical reactions, solutions, ideal and real monoatomic and polyatomic gases, equilibrium constants in gaseous phase, lattices, absorption etc. Freely available software is used for visualization and calculations on the course.

After completing the course KJEM140 the student should be able to:

• perform simple quantum mechanical calculations on small molecules.
• explain how molecular information can be obtained using spectroscopic methods on simple system.
• show and explain the connection between molecular properties and macroscopic termodynamical properties via statistical mechanics.
• perform simple statistical calculation on assemblies of molecules.
