摘要

Line strengths and nitrogen (N₂)-broadening coefficients for six nitrous oxide transitions were measured using a continuous-wave quantum cascade laser (cw-QCL) operating near 4.56 μm. The temperature dependence of the exponent n for the N₂-broadening coefficients was determined over the range 298–800 K using a sapphire-sealed optical cell. Spectral parameters were determined by fitting absorption spectra with multi-peak Voigt profiles. The line strengths for the six transitions are 0–3% larger than those in the HITRAN 2012 database, while the N₂-broadening coefficients at the reference temperature are 2–5% smaller than the HITRAN 2012 values.
