Contract Period : 12 months
Expected date of employment : 15 July 2025
Proportion of work : Full Time
Remuneration : Gross monthly salary between €3,021.50 and €3,451.50 depending on experience

Section(s) CN : 04 - Atoms and molecules, optics and lasers, hot plasmas
Missions
The objective of the postdoctoral researcher will be to develop 2D millimeter wave spectroscopy to: 1) disentangle the complicated spectra of radicals with large amplitude motion and 2) study the collisional dynamics of molecules of astrochemical interest. These objectives fall under the ANR contract 2D CORTICO.
Activities
-Develop code for programming the 2D spectrometer acquisition and analysis
-Producing radicals through either pulsed laser photolysis or hydrogen abstraction via radio frequency discharge
-Assignment of the rotational spectra of observed molecules and measuring collisional effects of molecules
-Communication of results through posters, presentations, and articles
Skills
We are looking for recent PhD graduates or young postdoctoral researchers in Physics, Chemistry or related fields. Those that have experience in chirped pulse Fourier transform millimeter wave spectroscopy, pulsed lasers, vacuum hardware, computer programming, and communicating results through publications and scientific presentations are encouraged to apply. Communication in English is required.
Work Context
Molecular spectra are used to detect molecules in space, enabled through laboratory studies of molecules of astrophysical interest. Updating experimental techniques for better production of unstable species could enable the detection of radicals with large amplitude motion in the interstellar medium. The experimental studies of the effects of collisions on astrochemical species is also lacking as new experimental techniques need to be developed to investigate these mechanisms.
