The infrared spectrum of N2O in the region between 1100 and 1440 cm−1 has been studied at 0.005-cm−1 resolution with a Fourier-transform spectrometer. Measurements were made of line positions of the species 14N216O, 14N15N16O, 15N14N16O, 14N218O, 14N217O, and 15N216O for several ground-state and hot bands. The observed line frequencies were analyzed to obtain values of band centers and upper- and lower-state rotational constants. Measurements from other studies covering the pure rotational region and the ν2 region were used in some of the analyses. Results from the least-squares fits for the 0200–0000, 0310–0110, 0400–0200, and 0420(e)–0220(e) bands of the 14N16O2 molecule indicate that the high J levels of the upper states of those bands are perturbed, mainly because of a vibration–rotation interaction (l-type resonance) between the respective upper states and close-lying states of the same vibrational type with Δl = ±2.

Table 5
Upper-State Effective Rotational Constants of Bands of the Rare Isotopic N2O Species (in cm−1)
Measurements of transitions with J less than 12 (microwave) were taken from Ref. 16, whereas those of J greater than 13 (submillimeter) were taken from Ref. 17. Calculated frequencies from constants obtained in this study.
O–C, observed minus calculated, are multiplied by 1000.

O–C, observed minus calculated, are multiplied by 100,000. Calculated values derived from constants given in this study.
Values given in parentheses are uncertainties in the last digit(s).
1, From combination differences of measurements in this work and microwave observed frequencies given by Pearson et al.,16 submillimeter measurements by Andreev et al.,17 and measurements in the 0110(e)–0000 and 0110(f)–0000 bands by Jolma et al.15; 2, from measurements in the 0220(f)–0110(f) band by Jolma et al.15 and combination differences in this work; asterisk, the constant L = −10.5(10)E-18 for the 0220(f) state of the 446 molecule; 3, from combination differences of measurements in this work; 4, from analysis of the 0001–0000 band in this study, details to be published; 5, from Amiot12 and measurements in this work; 6, see Amiot.13
Values given in parentheses are uncertainties in the last digit(s).

Table 5
Upper-State Effective Rotational Constants of Bands of the Rare Isotopic N2O Species (in cm−1)
Measurements of transitions with J less than 12 (microwave) were taken from Ref. 16, whereas those of J greater than 13 (submillimeter) were taken from Ref. 17. Calculated frequencies from constants obtained in this study.
O–C, observed minus calculated, are multiplied by 1000.
