Abstract
The absorption spectra of seven isotopologues of NNO (14N14N16O, 15N14N16O, 14N15N16O, 14N14N18O, 15N15N16O, 15N15N18O, and 15N14N18O) are studied in the range of 4200–6500 cm−1 with a Bruker FS-125M Fourier spectrometer, using a sample consisting of NO (80% 15N18O and 20% 14N16O) and a small number of N2O isotopologues. The error in measuring line centers is 0.0003 cm−1, and the error in measuring the intensities of lines is 5–15%. The spectroscopic constants of the 27 bands are determined by fitting the line contour parameters to the measured data set. It is noted that the standard deviation of the measured line centers from ones calculated (0.0005–0.0027 cm−1) is close to the experimental error.
