Experimental 2CH excitation in acetylene-containing van der Waals complexes

摘要

Spectroscopic results are presented concerning the 2CH excitation around 1.5 µm in van der Waals complexes of acetylene (C₂H₂) with Ar, Kr, N₂, CO₂, N₂O and C₂H₂. Many are reviewed from the literature, with some updates. Previously unpublished results are also presented, concerning the mechanism of formation of C₂H₂-Ar in the supersonic jet, the assignment of new spectral structures in C₂H₂-N₂O, and the first observation of 2CH excitation in C₂H₂-Ne, C₂H₂-H₂O, C₂H₂-D₂O and (C₂H₂) _n . Lifetimes of these 2CH vibrationally excited dimers are discussed.View full textDownload full textKeywordsvan der Waals complexes, acetylene, overtone spectroscopy, supersonic expansion, cavity ring-down 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/10.1080/00268976.2012.705347
