In this thesis, we studied two different types of photochemical reactions. On one hand, we determined non-radiative decay mechanisms for uracil molecule, which is part of the RNA. We then studied some derivatives of uracil (5-fluorouracil and 5- and 6-aminouracil) in order to explain their longer excited states lifetime relative to the parent system. It also allowed us to confirm our initial hypothesis. A second part of our work was about the Intramolecular Charge Transfer (ICT) in the benzonitrile family. Three derivatives of the DMABN have been studied: bicycle systems, 4F-DMABN and DTABN isomers. These systems allowed us to check both electronic and steric effects as well as to explain the mechanisms controlling the potential dual fluore...
