FIR-Carbons
In association with the AILES beamline of synchrotron SOLEIL,, we developed a multipass cell which optics permit to reach about 150 meters absorption pathlength. The set-up is designed to study the rotationally resolved spectra of relatively large C-bearing molecules (such as PAHs, diamondoids, and biphenyls) in the far-IR spectral region using the synchrotron continuum and the Fourier Transform interferometer of the AILES beamline. More generally, the high sensitivity of this experimental ensemble allows to carry out numerous projects dedicated to high resolution spectroscopy of non-reactive (or weakly reactive) molecules in the far-infrared region.
