Scientific Program:
There were be 10 plenary lectures and 3 mini-symposia with 10 invited speakers. Parallel sessions will feature 72 contributed talks. There will be four poster sessions with more than 130 contributions. The scientific fields covered are:
- High resolution rotational, vibrational, and electronic spectroscopy of molecules (radicals, ions, complexes, clusters, …)
- Molecular dynamics
- Theory assisting the prediction, simulation, and interpretation of spectra
- New techniques for high-resolution spectroscopy
- Applications to atmospheric sciences, astrophysics, planetology, combustion, gas-phase biomolecules, metrology and fundamental physics, cold molecules, etc.
