Mål

Kunskap och förståelse

För godkänd kurs skall doktoranden

• Be able to describe how a molecule interacts with electromagnetic radiation via electric dipole transitions and Raman scattering processes.
• Be able to describe how temperature and molecular symmetry can affect this interaction.
• Be able to explain the principles of interaction with rotational, vibrational, and electronic states for some of the simple molecules.
• Be able to describe and compare advantages and disadvantages with different technologies for different wavelength regions from microwaves to the X-ray

Färdighet och förmåga

För godkänd kurs skall doktoranden

• Be able to analyze molecular spectra for diatomic and polyatomic molecules.
• Be able to calculate different parameters such as temperature and moment of inertia from a spectrum of a diatomic molecule.
• Be able to decide the symmetry characteristics of diatomic and some simple polyatomic molecules based on the analysis of different spectra for IR and Raman scattering.
• Be able to write laboratory reports with a thorough analysis of measurement data.
• Be able to orally and in writing summarise a written project assignment. The written assignment can be of investigating nature on how molecular spectroscopy can be applied within science, industry, or society.
• Be able to solve assignments that require the use of information from other sources than the course material, e.g. via the Internet and databases.

Värderingsförmåga och förhållningssätt

För godkänd kurs skall doktoranden Be able to extract the essential information in an advanced English textbook
