The course aims at delivering both theoretical and practical aspects of fundamental molecular theory and practical molecular spectroscopy

Knowledge and understanding
For a passing grade the student must

be able to describe how a molecule interacts with electromagnetic radiation by means of electric dipole transitions and Raman scattering processes.

be able to describe how temperature and molecular symmetry may affect the interactions.

be able to explain the principles for interactions with rotational, vibrational and electronic energy levels of simpler molecules. Describe and compare advantages and drawbacks of different techniques applied to wavelength regions ranging from microwaves to X-rays.

Skills and abilities
For a passing grade the student must

be able to analyze spectra of diatomic and polyatomic molecules.

be able to calculate parameters such as temperature and moment of inertia from spectra of diatomic molecules.

be able to determine the properties of symmetry of diatomic and some of the simpler polyatomic molecules based on the analysis of, e.g., IR- and Raman spectra.

be able to write a report from a laboratory exercise, analyze and evaluate the measured data.

make a written and oral presentation of a small project-like assignment. The assignment should be of an investigative character with respect to different applications of molecular spectroscopy that may be used in different fields of science, industry and society.

be able to assimilate the important information of an advanced English text book.

be able to solve tasks demanding information from sources outside the material given during the course, for instance using data bases provided by the internet.
