Femto-Fourier transform-cavity enhanced absorption spectroscopy in a supersonic expansion

摘要

Proofs of principle spectra of C₂H₄, N₂O and C₂H₂, including H12C13CH in natural abundance, are reported, recorded in the 1.6 µm 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 78 m and the optimal S/N is over 2300. The data processing is detailed. Saturation effects are reported for the C₂H₂ bands.View full textDownload full textKeywordscavity enhanced absorption, free supersonic expansion, Fourier transform spectroscopy, femto comb spectroscopyRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00268976.2012.701342
