Direct frequency comb spectroscopy of HCN to evaluate line lists

Faraday discussions, 2023
We report direct frequency comb spectroscopy of the 2ν1 band of H13CN in the short-wave infrared (λ = 1.56 μm) towards experimental validation of molecular line lists that support observatories like JWST.

High Accuracy Line Lists of CH4 and H2CO in the 8 μm Range from Optical Frequency Comb Fourier Transform Spectroscopy

2023 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2023
Spectral data in the 8 µm region - a water window where many molecules show strong rovibrational features - are currently derived mostly from conventional FTIR measurements, with line position uncertainties of the order of a few to few tens of MHz [1 ...

Expert List of Absorption Lines of the SO2 Molecule in the 2000–3000 cm–1 Spectral Region

Atmospheric and Oceanic Optics, 2020
A detailed high-accuracy list of the SO2 molecule absorption lines was obtained in the 2000–3000 cm–1 spectral region, which is important for atmospheric applications, based on a combination of the high-accuracy data on experimental energy levels and variational calculations of the intensities of vibrational-rotational transitions.

GOSAT-2014 methane spectral line list

Journal of Quantitative Spectroscopy and Radiative Transfer, 2015
Abstract The updated methane spectral line list GOSAT-2014 for the 5550–6240 cm −1 region with the intensity cutoff of 5×10 –25  cm/molecule at 296 K is presented. The line list is based on the extensive measurements of the methane spectral line parameters performed at different temperatures and pressures of methane without and with buffer gases N 2

GOSAT-2009 methane spectral line list in the 5550–6236cm−1 range

Journal of Quantitative Spectroscopy and Radiative Transfer, 2010
Abstract A methane spectral line list for the 5550–6236 cm −1 range with the intensity cut off 4×10 −26  cm/molecule at 296 K is presented. The line list is based on new extensive measurements of methane spectral line parameters performed at different temperatures and pressures of methane and buffer gases N 2 , O 2 and air.

List of references on spectral line analysis

Signal Processing, 1993
Abstract The spectral line analysis (SLA), also called line spectrum analysis, deals with the problem of extracting information on sinusoidal signals from noise-corrupted measurements. It has numerous applications in sonar, radar, underwater surveillance, communications, geophysical exploration, speech analysis, nuclear physics and other fields.

Improved spectroscopic line list of methyl chloride in the 1900–2600 cm−1 spectral region

Journal of Quantitative Spectroscopy and Radiative Transfer, 2016
Abstract Parameters of line positions and line intensities up to 2×10 –25  cm −1 /(molecule cm −2 ) for 12 CH 3 35 Cl and 12 CH 3 37 Cl were retrieved from the Fourier transform spectra in the range of 1900–2600 cm −1 . Line intensities were scaled with measurements from literature.

Empirical energy levels and line lists of HD17O and HD18O from the analysis of far infrared absorption spectra

Journal of Physical and Chemical Reference Data
Five far infrared absorption spectra of water vapor highly enriched in 17O, 18O and deuterium (D) are analyzed. The Fourier transform spectra at room temperature were recorded at the SOLEIL synchrotron facility with a 151.75 m absorption pathlength.

A spectral line list for water isotopologues in the 1100–4100 cm−1 region for application to CO2-rich planetary atmospheres

Journal of Molecular Spectroscopy, 2016
Abstract A line list of transitions for seven isotopologues of water vapor in the 1100–4100 wavenumber range has been constructed for application to atmospheres rich in CO 2 . The quantum transitions for H 2 16 O, H 2 18 O, H 2 17 O, HD 16 O, HD 18 O, and HD 17 O are from the 2012 HITRAN database (Rothman et al., 2013) and those for D 2 16 O are ...
