Line positions and N2-induced line parameters of the 00°3–00°0 band of 14N216O by comb-assisted cavity ring-down spectroscopy

•The spectrum of 00°3 – 00°0 band of 14N216O is studied with a laser-locked cavity ring-down spectrometer referenced to an optical frequency comb.•88 line positions are determined with an uncertainty below 1.0 MHz.•N2-induced broadening and shift coefficients of 20 isolated lines were retrieved with the voigt and quadratic speed-dependence voigt profiles.•Comparisons of line parameters determined in this work with those given in literatures are discussed.
