Abstract

The N₂O infrared spectrum in the 900–1090- and 1580–2380-cm⁻¹ regions was studied at a 0.005-cm⁻¹ resolution with a Fourier-transform spectrometer. Measurements were made of line frequencies of the species ¹⁴N₂¹⁶O, ¹⁴N¹⁵N¹⁶O, ¹⁵N¹⁴N¹⁶O, ¹⁴N₂¹⁸O, ¹⁴N₂¹⁷O, ¹⁵N₂¹⁶O, ¹⁴N¹⁵N¹⁸O, and ¹⁵N¹⁴N¹⁸O for several ground-state bands and hot bands. A few of these bands are reported for the first time to the author’s knowledge. The observed line frequencies were analyzed to obtain values of band centers and upper-state effective rotational constants. Results from the least-squares fits for the 0400–0000, 0420(e)–0000, and 0510–0110 bands of the ¹⁴N₂¹⁶O molecule indicate that the high-J levels of the upper states are perturbed. Resonance interactions were observed in transitions in the 1001–1000 band of ¹⁴N₂¹⁶O and ¹⁵N¹⁴N¹⁶O and the 1111(f)–1110(f), 0600–0200, 0600–1000, and 0620(e)–1000 bands of ¹⁴N₂¹⁶O.
