2002年6月1日 · High resolution FTIR observations were performed to measure the concentration of tropospheric trace gases in the Arctic at Spitsbergen (79°N, 12°E) and at mid latitudes in Potsdam (53°N, 13°E) using the sun or moon as the infrared light source. We focus the interest in this paper on two short-lived gases in the atmosphere, CH 2 O and C 2 H 2.

Acetylene (C 2 H 2) Molecular weight 26 amu Freezing point -81.8 C Boiling point 84 C HITRAN number: 26 Infrared cross-sections from PNNL FTIR infrared cross-sections from 600 to 6650 cm -1 Data available at 5 C, 25 C, and 50 C Spectra is composite of on the order of 10 different pressures,backfilled with nitrogen to 760 T.

2023年1月20日 · Unlike the other four species, the FTIR measurements show that there is almost no seasonal variation in the CO column. The correlation coefficients (R) between the synoptic variations in CO and the other four species (C2H2, C2H6, H2CO, and HCN) are between 0.68 and 0.80, indicating that they are affected by common sources.

2007年2月19日 · Spectra are recorded with a Fourier-transform infrared spectrometer (FTIR) (Bruker IFS120HR) at 0.0043 cm −1 resolution (defined as 0.9/ δ, in which δ is the maximum optical path difference). Multipass optics around the expansion leads to an increase of signal to noise ratio ∼5 times over single pass.

1999年8月7日 · The production of acetylenic compounds (C 2 H x) seems to be a key mechanism for the powder formation in all the investigated hydrocarbon plasmas. Electron attachment to acetylenic compounds and the following ion-neutral reactions might lead to the high-mass carbon anions, which are trapped in the plasma and finally end in powder formation.

Variations of CH2O and C2H2 determined from groundbased FTIR measurements and comparison with model results

A first order comparison with local ground-based Fourier transform infraRed (FTIR) measurements has been carried out allowing tests of seasonal consistency which is reasonably captured, except for HCN at Jungfraujoch. The IASI data …

This research has performed preliminary in situ Fourier transform infrared (FTIR) measurements during the plasma deposition of amorphous silicon (a‐Si:H). Experiments demonstrate both gas phase and…
