N2Broadening in the13C16O 2–0 Band around 4167 cm−1

N2broadening coefficients have been measured for 65 lines of the13C16O 2–0 band using a Fourier transform spectrometer. These lines are located in the spectral range 4011–4252 cm−1. The spectra were recorded with 99% isotopically pure13CO in a White-type cell at a resolution of 0.005 cm−1. Voigt profiles convolved with the FTS apparatus function were fitted to the experimental lineshapes using a nonlinear least-squares fit technique. From the fits the Lorentzian HWHM was determined as function of N2pressure. Pressure broadening coefficients formbetween −33 and +34 were obtained with uncertainties of 5.8%. The results are compared to earlier published N2broadening coefficients and our measurements in the 2–0 band of12C16O. To our knowledge this is the first investigation of13CO pressure broadening.
