The Francis Perrin Laboratory carries on research in the field of physical chemistry. A large part of the projects is dedicated to the interaction between light (UV-visible-IR) and molecular systems and are pursued along four interconnected objectives:

  • Describe the fundamental processes involved when light interacts with a molecular system, e.g. processes relevant to femtochemistry or induced by collective effects (biomolecules, clusters)
  • Unravel the mechanisms underlying natural phenomena, such as protein folding or carcinogenic mutations, by using light
  • Contribute to the development of nanoscience and nanotechnology
  • Elaborate new applications in the field of environment, alternate energy resources, health…
