In this thesis, I review my own contributions in the field of computational photochemistry. This manuscript is written as an introduction to this field of research. It is not intended to be a textbook, as more emphasis has been made on illustrations rather than on methodologies and technical guidelines. In this way, I hope that it will be accessible to a large audience, from undergraduate students to more experienced scientists who would be interested in learning about this fascinating and relatively young field of research.
