Résumé :

Proofs of principle spectra of C2H4, N2O and C2H2, including H12C13CH in natural abundance, are reported, recorded in the 1.6 mm range in an Ar supersonic expansion using femto-Fourier transform-cavity enhanced absorption spectroscopy. The effective absorption pathlength in the jet-cooled sample is up to 78m and the optimal S/N is over 2300. The data processing is detailed. Saturation effects are reported for the C2H2 bands. spectroscopy © 2012 Taylor and Francis.
