Lecture 4. Photoelectron spectroscopy:  Chemical and Biological applications. Chemical shift of core-level. Born-Oppenheimer approximation. Vibrational and rotational structure. Translational and rotational Doppler effects. Young’s double/multiple slit interference.

Lecture 5. Quantum dynamics. Wave packet of free motion and wave packet in harmonic potential.

Lecture 6. Optical and X-ray absorption spectroscopy of atoms and molecules. Applications. NEXAFS  spectroscopy. Structure of the continuum wave function.  EXAFS spectroscopy: structure determination of disordered systems.

Lecture 7. Coincidence spectroscopy as a tool to study fixed in space molecules.

Applications.

Lecture 8. Time-dependent theory of the light scattering. Resonant and non-resonant optical and X-ray Raman scattering.  Resonant Auger spectroscopy.

Lecture 9. Dynamics versus interference. Lifetime vibrational and rotational interference. Scattering duration versus the detuning. Reversible and irreversible quenching of the wave packet of excited state.

Lecture 10. Apllications of Raman and Auger spectroscopies.

Lecture 11. Stimulated emission and Lasing. Non-linear spectroscopy. Rabi solution and Rabi oscillations. X-ray free-electron laser and overview of its applications¨.

Intended learning outcomes *

After a successful course completion, the student will be able:

1) to know general principles of different types of optical and X-ray spectroscopies;

2) to be able to use both dynamical and time-independent approaches in spectroscopy;

3) to know the meaning of the wave packet and to be able to solve time dependent Schrödinger equation for free propagation and harmonic potential;

4) to derive the Fermi-Golden rule and  the rates of absorption, photoionization, emission and Auger processes;

5) to know how the X-ray ionization and absorption spectroscopies give the structure information;

6) to model resonant X-ray Raman and Auger  scattering taking into account both electronic and nuclear degrees of freedom;   

7) to model the interaction of molecules with strong electromagnetic field.
