“…In all cases, our results agree well with Dhyne et al [17] with a maximum difference of about 2%. We have also compared our results with Arteaga et al [38] who reported N 2 -broadening coefficients for ν 1 +ν 3 band over the same rotational quantum numbers as our measurements in ν 4 +ν 5 band. Arteaga et al [38] measurements are also found to be in good agreement with our results.…”

Arteaga et al [38] measurements are also found to be in good agreement with our results. In Table 3, we report measurements of Ar-broadening coefficients (2γ C2H2-Ar ) in the ν 4 +ν 5 band at room temperature (296 K) deduced from Voigt, Galatry and Rautian profiles.…”

“…Values obtained using Galatry and Rautian profiles are larger than the corresponding ones resulting from the Voigt profile by about 4%. Our measurements are compared in Table 4 with Arteaga et al [38] data for ν 1 +ν 3 band and the calculations performed by Thibault [39] for the R-branches of acetylene. Excellent agreement is seen among our measurements, Arteaga et al [38] data and Thibault [39] calculations with a maximum difference of about 1.5%.…”

“…To our knowledge, this study reports the first measurements of Ar-broadening coefficients for ν 4 +ν 5 band of acetylene. Previous Ar-broadening studies performed in other spectral regions of acetylene include Bouanich et al [35] for ν 5 band and Arteaga et al [38] for ν 1 +ν 3 band.…”

Measurements of linestrengths, N2-, Ar-, He-and selfbroadening coefficients of acetylene in the 4+5 combination band using a cw quantum cascade laser KAUST Repository AbstractLinestrengths, N 2 -, Ar-, He-and self-broadening coefficients of acetylene have been measured at 296 K in the P branch of the ν 4 +ν 5 combination band for 25 rotational transitions. The effect of gas temperature is studied over 296 -683 K for five transitions to allow the determination of the temperature dependent exponent n for N 2 -and Ar-broadening coefficients. These measurements were performed using a continuous-wave quantum cascade laser (cw-QCL) operating over 1253 -1310 cm -1 . Spectroscopic parameters were obtained by fitting absorption spectra using Voigt, Galatry and Rautian profiles. Linestrength and broadening results are compared with previous studies available in literature for the ν 4 +ν 5 combination band and other vibrational bands of acetylene.

“…Much less attention has been paid to the molecular-broadening of acetylene lines. Experimentally, N 2 -, O 2 -, H 2 -pressure broadening [6,[15][16][17][18][19][20][21][22] and self broadening pressure coefficients [6,15,23] have been measured at various temperatures between 147 and 300 K.…”

In this work we present a theoretical and experimental study of the acetylene -hydrogen system.A potential surface considering rigid monomers has been obtained by ab initio quantum chemistry methods. This 4-dimensional potential is further employed to compute using the close-clouping approach and the coupled-states approximation pressure broadening coefficients of C 2 H 2 isotropic Raman Q lines over a temperature range of 77 to 2000 K. Experimental data for the acetylene ν 2 Raman lines broadened by molecular hydrogen are obtained using stimulated Raman spectroscopy.The comparison at 143 K of theoretical values with experimental data is promising. Approximations to increase computational efficiency are proposed. *
