Abstract
- Abstract: The absorption spectrum of the natural sample of nitrous oxide has been recorded at Doppler limited resolution with a Fourier-transform spectrometer in the spectral range 5000–10000cm−1. Ten cold bands (8Σ−Σ and 2Σ−Π), thirteen hot bands (11Π−Π, Σ−Σ, and Δ−Δ) of 14N2 16O and the 3ν 3 band of 14N15N16O have been newly detected. The uncertainty of the line position determination is estimated to be about 0.005cm−1 for unblended lines. The assignment of the spectrum has been done with the help of the prediction performed within the framework of the polyad model of effective Hamiltonian. The spectroscopic parameters G v , B v , D v , H v , and q v have been determined for all newly detected bands. The line intensities of 13 weak bands have been measured. The uncertainty of the obtained line intensity values varies from 7 to 13%. [Copyright &y& Elsevier]
