N2O vibration-rotation parameters derived from measurements in the 900-1090- and 1580-2380/cm regions

Fourier-transform spectrometric measurements of the N2O IR spectrum in the 900-1090 and 1580-2380/cm regions were obtained at a 0.005/cm resolution, and line frequencies of eight species for several ground state bands and hot bands are analyzed to obtain values of band centers and upper-state effective rotational constants. Several bands are reported for the first time. Least-squares fits for the 0400-0000, 0420(e)-0000, and 0510-0110 bands of the (N-14)2O-16 species suggest perturbation of the high-J levels of the upper states. Resonance interactions were noted in transitions including the 1001-1000 bands of (N-14)2O-16 and N-15N-14O-16.
