Course: Vibrational Spectroscopy

Department/Abbreviation: KBF/NVS

Year: 2020

Guarantee: 'doc. RNDr. Karolína Machalová Šišková, Ph.D.'

Annotation: Purpose of this course is an introduction to selected fields of vibration spectroscopy - from the origin of molecular spectra to theoretical computing. The main goal is the interpretation of vibrational spectra which can be used in the framework of Bc, Diploma and PhD Theses.
