Learning outcomes
|
The student will study excitation and deactivation of molecules (light, electronic excited states, absorption spectrum, Jablonski diagram, effect of order of pi,pi* and n,pi* states on luminescence, transfer of electron excitation energy, measurement of absorption/luminescent spectra), kinetics of photo-physical and photochemical processes, theoretical organic photochemistry, photo-isomerization and rearrangement, and photochemical reactors.
The student will be instructed on basics photochemical terms and principles.
