Content and learning outcomes

Course contents

Grating spectrometers. Principles of molecular transitions. Laser spectroscopy. Laser induced fluorescence. Experiments on iodine. Time-resolved spectroscopy and measurements on molecular iodine and its life-time. Laser induced breakdown spectroscopy. Measurements on metal samples. Determinations of elemental concentrations. Laser Raman spectroscopy and measurements on liquid nitrogen. Use of Notch filters. Infrared spectroscopy. Measurements on carbon monoxide. Determination of rotational constants. Synthesizes of molecular spectra from molecular constants.

Intended learning outcomes

The course aims to give basic knowledge about advanced experimental physics, such as the use of modern IR spectrometers, high resolution spectrometers, laser measurement methods as LIBS (Laser induced brekdown spectroscopy)  and Laser Raman spectroscopy. After the course the student will be able to:

  • perform experiments on rotation and vibration spectroscopy
  • use LIBS technology to measure concentration of metals
  • use laser induced fluorescence techniques to measure vibrational constants
  • use Laser Raman techniques on larger molecules in the liquid phase
  • synthesizes of  molecular spectra with known molecular constants
  • use laser spectroscopy to measure vibrational and rotational temperatures
  • perform calculations applying the Franck-Condon approximation

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
