CAMPE is a laboratory for fundamental research combining chemists specializing in synthesis, theoreticians specializing in molecular modeling, spectroscopists and specialists of instrumentation. The laboratory undertakes research in chemistry and molecular physical chemistry, focusing on the CEA's major programs: new technologies for energy, the nanosciences, and chemistry for health and the environment. These themes are treated following an integrated and complementary approach in synthesis, physical chemistry, advanced spectroscopy and theory and modeling. Research interests include photochemistry, catalysis, the development of new carbonaceous materials for battery electrodes or supercapacitors, as well as the study of complex paramagnetic systems (polyradicals, active sites of metalloproteins).

The EPR team is composed of four tenure staff:
Serge Gambarelli, Vincent Maurel, Jean-Marie Mouesca (CEA researchers), and Christian Lombard (CEA Engineer) working with a regularly renewed group of undergraduate and graduate students and post-doctoral research assistants. The group has developed a strong expertise in pulsed EPR techniques (Electron-Spin Echo Envelope Modulation (ESEEM), Hyperfine Sublevel Correlation Spectroscopy (HYSCORE) and pulsed Electron Nucleus Double Resonance (ENDOR) at 9 GHz and 35 GHz). We have also developed dedicated setups for time-resolved EPR and the study of light-induced phenomena.

These techniques have been successfully applied to a wide variety of systems including paramagnetic catalytic centers in chemistry (organometallic complexes and quantum dots) and biology (metalloproteins), as well as organic or organometallic systems with coupled electronic spins such as high spin polymers. The results of these pulsed EPR experiments are systematically supported by DFT calculations. This approach combining pulsed-EPR techniques with DFT calculations is one of the strong points of our laboratory, and has been recognised as such by successful applications for funding. The laboratory has a cutting-edge set of EPR spectrometers including a 9 GHz and 35 GHz pulsed machine with ELDOR and ENDOR capacities, as well as five other continuous wave (CW) machines.

The work of our team, in collaboration with national and international groups, has given rise to over 100 publications, including some very high profile articles.
