Thursday March 2
Brushup of your knowledge of statistical
thermodynamics, especially the basics of
microcanonical ensemble, calculation of the molecular canonical partition
function and the calculation of the equilibrium constant from the canonical
partition function.
To learn: your notes, and
The statistical thermodynamics Chapter of the
textbook Chemical Thermodynamics.
Auxiliary material:
A presentation (in Hungarian) of statistical
thermodynamics within the course Physical Chemistry 1. The thermodynamics
textbook of H. B. Callen.
Thursday March 9
Theories of elementary reactions
based on statistical physics: Collision theory, Potential Energy Surfaces (PES)
and the Transition State Theory (TST) based on the quasiequilibrium
approximation. TST based on a dynamic approximation on a PES, and
quantum dynamical simulations without invoking the BornOppenheimer
approximation and PES.
To learn: your notes, Chapters 1 and 2 (pp. 137) of the Textbook; a
booklet on rate theories (or pages 125
of the
Hungarian kinetics notes), and Chapter 3 of the
Pilling book / its
Hungarian edition.
Auxiliary material:
A historical overview of the development of theories can
be found in Hungarian in MKL p. 368, in
English in the manuscript sent to Polanyiana.
Thursday March 16
Experimental methods used to study chemical
kinetics: "classical" methods, discharge flow, continuous flow and stopped flow
reactors, relaxation methods. Methods of detection: resonance fluorescence,
laser induced fluorscence, mass spectrometry. Shock tubes. Flash photolysis and
laser photolysis.
To learn: your notes, the presented
material, Chapter 7 (pp. 161181) of the Textbook;
and Chapter 2 of the
Pilling book / its
Hungarian edition. A booklet on
elementary kinetics, where the last pages discuss pseudofirstorder
reactions in more details (or pages 3941 of the
Hungarian kinetics notes).
Thursday March 23
Reaction dynamics: Interaction potentials and the harpoon
mechanism. Early experimental methods: large experimental setups for molecular
beam collisions. Recent experimental setups: laser beams and their interaction
with bulk mixtures and molecular beams. Stateselective excitation and
stateselective detection.
To learn:
your notes, a
booklet on rate theories (or pages 125
of the
Hungarian kinetics notes), and Chapter 4 of the
Pilling book / its
Hungarian edition.
Thursday March 30
Guest speaker: András Szanthoffer
Topics:
Theories of unimolecular reactions.
To learn: Chapter 5 of the
Pilling book / its
Hungarian edition + your notes.
Auxiliary material:

Thursday April 13
Kinetics of reactions in solution: General considerations
concerning the difference between condensed phase reactions and gas phase
reactions. Electrostatic interactions of ions and dipole molecules and their
contributions to the energetics of reactions. The effect of activity on the rate
of reactions ("primary salt effect").
To learn: your notes and Chapter 6 of the
Pilling book /
its Hungarian edition.

constants. Activation controlled and diffusion controlled reactions. Combined
effect of activation and diffusion control..
To learn: your notes and Chapter 6 of the
Pilling book / its
Hungarian edition.
Auxiliary material:

Fotochemistry. Basic events in photochemical reactions. Photochemical
principles and experimental methods. Some everyday photochemical /
photobiological applications. (e. g. beer chemistry, the mechanism of suntan,
etc.)
To learn: Chapter 12 of the
Pilling book / its
Hungarian edition + your notes.
Auxiliary material:
