Summary

This course presents the theoretical bases of electronic spectroscopy and molecular photophysics. The principles of the reactivity of excited states of molecules and solids under irradiation are detailled. The main classes of industrial and natural photochemical processes are finally described.

Content

1. Fundamentals
Introduction - Light absorption and reflection - Radiation and molecular orbitals - Photonics of solid materials.

 

2. Photophysical processes
Excited states deactivation pathways - Kinetics of radiative and nonradiative processes - Excimers and exciplexes - Intermolecular electronic energy transfer - Photosensitization.

 

3. Photochemical reactions
Photodissociation - Multiphoton processes - Photoinduced elec-tron transfer - Pericyclic concerted reactions.

 

4. Organic synthetic reactions
Reactions of ethenes and aromatic compounds - Photo-chemical reactions of the carbonyl chromophore - Photo-oxygenation (singlet oxygen, superoxide anion).

 

5. Polymer and pigments photochemistry
Photopolymerization and cross-linking - Photodegradation and stabilization of polymers and pigments.

 

6. Natural photochemical processes
Light-induced atmospheric reactions - Natural photosynthesis - Mechanisms of vision.
