Synopsis:

Description of the interaction of atoms and molecules with electromagnetic radiation in the optical region. Basic experimental techniques of optical spectroscopy.

Requirements:

The course concludes with an oral exam demonstrating knowledge of the discussed spectroscopic methods, especially their physical principles, experimental design, and the nature of the information they provide about the sample.

Syllabus of lectures:

Basic topics:

1. Energy levels in atoms and molecules; Interaction with electromagnetic radiation; Spectroscopic transitions; Transition moments; Selection rules

2. Basic spectroscopic and photometric quantities; Shape of spectral lines; Homogeneous and inhomogeneous broadening

3. Fundamentals of instrumentation (radiation sources, detectors, optical materials); Dispersive spectrometers vs. Interferometers; Single-channel vs. multi-channel detection

4. Atomic absorption and emission spectroscopy (flame and ICP AAS, ICP OES)

5. UV-Vis absorption spectroscopy; Color of substances; Luminescence spectroscopy; Luminescence quenching; Non-radiative relaxation processes

6. Infrared absorption spectroscopy; Raman scattering spectroscopy
