The project is the main part of the PhLAM activity in a national research project (ANR ASTRID) entitled METIS « Millimeter-wave Explosive Taggant vapors Investigations using Spectral taxonomy ». The main objective of METIS is the development of an ultra-sensitive mm-wave absorption spectrometer, required to provide a new approach for the detection and the discrimination of explosive taggants in the gas phase. The research group at PhLAM laboratory is in charge of the mandatory preliminary step of providing a prediction of the millimeter-wave spectra of selected explosive taggants as accurate as possible. For this purpose, Fourier Transform MicroWave (FTMW) spectroscopy in jet-cooled conditions offers the high sensitivity and high selectivity necessary for the detection of gas traces such as explosive taggants.
The candidate will be in charge of:
- quantum chemistry calculations necessary for the prediction and analysis of the rotational spectra,
- measurements of the microwave spectra using the supersonic jet FTMW spectrometers
- the analyses and simulations of the recorded rotational spectra using the appropriate software freely made available to the academic community.
Finally, deduced accurate molecular parameters and dataset will be used to analyse and simulate the challenging room temperature mm-wave spectra of these explosive taggants.
The candidate should have a PhD in molecular spectroscopy and/or in quantum chemistry for spectroscopic applications. He/she should have expertise in one or more of the following fields:
- microwave spectroscopy,
- high-resolution spectroscopy analysis,
- electronic structure calculations,
- in addition, instrumental development and/or computer skills will be appreciated.
General expectations from a postdoctoral researcher:
- Perform research on the assigned topics in collaboration with colleagues,
- Write progress reports, write and publish research articles in international journals,
- Present the work in conferences/meetings.
Within the PhLAM laboratory, the Molecular Physics at Interfaces (MPI) team is involved in research themes at the interface of molecular physics and various fields of application such as astrophysics, environmental sciences, biology, medicine, plasmas and materials (https://phlam.univ-lille.fr/recherche/pmi/). In the vast majority of cases, the experiments, spectral analyzes, quantum calculations and interpretations are carried out by the group itself, giving it the particularity of being able to carry out studies "from the begining to the end". In more complex cases, the network of collaborations built over the years makes it possible to call on chemists for syntheses, experimentalists for recordings in other spectral ranges, spectroscopists for specific spectral analyzes or theoreticians for more sophisticated calculations. The "Defense" application is a recent theme resulting from a sustained collaboration with the LPCA laboratory at Dunkirk.
