Line positions and N2-induced line parameters of the 00°3-00°0 band of 14N216O by comb-assisted cavity ring-down spectroscopy
Abstract
Ro-vibrational transitions of the 00°3-00°0 band around 1.52 μm with line intensities in the order of 10-24 to 10-23 cm-1/(molecule·cm-2) have been recorded using a comb-assisted laser-locked cavity ring-down spectrometer with high sensitivity as well as high precision. In total, 88 line positions were determined with a sub-MHz uncertainty (1-σ), better than previous experimental results by 1-2 order of magnitude. N2-induced line shape parameters of 20 isolated transitions were derived by using the Voigt profile and the quadratic Speed-Dependent Voigt profile with relative uncertainties of 1-2% (1-σ). Comparisons of the line parameters determined in this work with literature experimental values are given.
