We performed a detailed numerical uncertainty quantification of the fixed-and scanned-
wavelength direct absorption spectroscopy method (DA) at high temperature. A transition …

High-temperature line mixing behavior was studied for 15 R-branch line manifolds in the v 3
band of methane from 3.14 µm to 3.28 µm. The temperature-dependence of the line mixing …

Using a high-resolution mid-infrared dual-comb spectrometer operating in the 1300 cm− 1
spectral region, spectra of acetylene were recorded at room temperature. Spectroscopic …

This work theoretically studied the spectral line shape of H 2 O perturbed by Ar in the
temperature range of 20–300 K for the pure rotational lines below 360 cm− 1, as well as …

This work studied the rovibrational absorption spectral line-shape parameters of the P (1)–P
(10) and R (0)–R (9) lines for Hydrogen fluoride perturbed by argon in the 0–0, 1–0, and 2–0 …

In this study, aluminum oxy-hydroxide (boehmite) was synthesized using the co-precipitation
method and two phases gamma and alpha alumina were prepared from boehmite by …

Wavelength modulation-direct absorption spectroscopy (WM-DAS) has been used to
measure the absorption line shapes of the H 2 O transition at 7299.431 cm− 1 and the CO …

A novel method of Lorentz distribution solution (LDS) from overlapped absorbance profile in
time domain (incomplete absorbance profile in frequency domain) based on the direct …

A method based on direct absorption spectroscopy (DAS) without baseline fitting procedure,
which we called baseline-free DAS (BFDAS), is proposed. The BFDAS utilizes three …

Absorption lineshapes for 10 CH 4 transitions in the v 2 and v 4 band were measured at high-
resolution in a thermodynamically-controlled optical cell using a quantum cascade laser …
