Absolute Intensities Measurements in the ν4 + ν5 Band of 12C2H2: Analysis of Herman–Wallis Effects and Forbidden Transitions

Fourier transform measurements of water vapor line parameters in the 4200–6600cm−1 region

“…Three different programs: WSPECTRA [40], BFIT [41] and MULTIFIT [42] were used to fit the lines depending on the type of spectrometer and the density of the lines in a given region. The first one, which runs directly from the Bruker output format, fits the observed lines one-byone to the exponential of a theoretical profile (Voigt in this case) convolved by the instrumental function as described in our previous study [2].…”

Measurements of linestrengths, N2-, Ar-, He- and self-broadening coefficients of acetylene in the ν4+ν5 combination band using a cw quantum cascade laser

“…From measurements made with tunable diode lasers, Devi et al [10] derived N 2 -and air-broadening coefficients for a total of 29 lines between 1250 and 1380 cm -1 in the P and R branches. Individual line intensities of acetylene in the P and R branches of the ν 4 +ν 5 combination band have been measured at room temperature using Fourier Transform Infrared (FTIR) Spectroscopy in a number of studies [11][12][13][14]. Among recent measurements of spectroscopic parameters of acetylene in the ν 4 + ν 5 combination band, one should note the studies performed by Lepère's group [15][16][17][18][19][20].…”

High resolution Fourier transform spectroscopy of HD16O: Line positions, absolute intensities and self broadening coefficients in the 8800–11,600cm−1 spectral region

“…Once the isotopologue was known, we used the Wspectra [34] and Bfit [35] softwares developed in ULB to adjust each line to a Voigt profile and determine the line positions, surfaces (integrated absorption coefficients) and Lorentzian widths. We then determined for each isotopologue the mean ratios of the line surface between two spectra, which is the ratio of the partial pressures.…”
