Missions
The postdoctoral fellow will carry out an experimental and theoretical study of intramolecular vibrational Stark effects in order to characterize them and use them for conformational assignment purposes. This original study will mainly consist of performing gas-phase IR laser spectroscopy of both neutral molecular systems cooled by a molecular beam and ionic systems in a cryogenic ion trap. This study will also include performing the quantum chemistry calculations necessary for interpreting the experimental results.
Activities
- IR laser spectroscopy experiments
- Quantum chemistry calculations
- Analysis and communication of results
Skills
- PhD in Chemistry or Physics, obtained in 2024 or 2025.
- Proficiency in one or more gas-phase experimental techniques (laser spectroscopy, mass spectrometry, electrospray ionization, ion trap).
- Prior experience in quantum chemistry calculations.
Work Context
The postdoctoral fellow will work within the SYSIPHE team at the Orsay Institute of Molecular Sciences (ISMO) at Paris-Saclay University. https://www.ismo.universite-paris-saclay.fr/structure-et-dynamique-des-systemes-complexes-isoles-photoexcites-sysiphe/
Activities will be spread across two experimental facilities of the SYSIPHE team and the Paris-Saclay computing mesocenter.
Applications will be considered until September 30, 2025.
