Molecular Spectroscopy 1200-2EN-MOSLE1M

Course Outline
Each lecture is a standalone module covering the following topics:

1. Introduction to Molecular Spectroscopy:
Energy quantization, types of energy, phenomena of absorption, emission, and scattering, transition probabilities, the concept of spectra, classification and characteristics of spectra, and criteria for the classification of spectroscopic methods.

2. Rotational Spectroscopy

3. Vibrational Absorption Spectroscopy (IR)

4. Raman Spectroscopy

5. Electronic Absorption Spectroscopy (UV-Vis)

6. NMR Spectroscopy

For each topic from 2 to 6 the course examines theoretical models related to the specific type of molecular energy, the characteristics of energy states, interactions with electromagnetic radiation, selection rules, spectral features, methodology, and applications.

Key Concepts Covered:
Ad. 2 Rigid rotor model, angular momentum quantization, rotational quantum numbers;
Ad. 3 harmonic and anharmonic oscillators, vibrational quantum numbers, normal modes, characteristic group frequencies, mutual exclusion principle;
Ad. 4 Rayleigh and Raman scattering mechanisms, polarizability, bond polarity criteria;
Ad. 5 quantum numbers (principal, orbital, magnetic, electron spin), vector model of the atom, term multiplicity, phosphorescence, luminescence, XPS and Auger spectra;
Ad. 6 nuclear magnetism, magnetic nuclei in an external magnetic field, resonance conditions, nuclear shielding, spin-spin coupling, chemical and magnetic equivalence, 1H and 13C NMR spectroscopy, 1D pulse experiment and signal detection principle, NMR signal processing, Fourier transform.
