AILES Beamline

Research Contents / Beamlines / Advanced Infrared Line Exploited for Spectroscopy - AILES

The AILES Beamline is dedicated to Infrared Absorption Spectroscopy for materials and molecules. The usefull spectral range spans from the Mid- to Far Infrared (IR) or Terahertz (THz) domains, but the best performance concern the 8 to 1000 cm-1 energy range, with a maximum resolution of 0.0008 cm-1.

Research on AILES involves molecular spectroscopy and studies of optical properties of materials. The concerned scientific community spreads from physics to chemistry and biology.

Infrared to support thermodynamics: characterization of the equilibrium between acetic acid and its dimer in the gas phase

Thanks to the Jet-AILES apparatus, French scientists managed to determine the dimerization free energy of acetic acid at room temperature. They used an analysis method based exclusively on infrared spectroscopy, thus ending the controversy on the ability of this technique to produce high-quality data for thermodynamics. [Full story]
