Title: High resolution analysis of three bands of the electronic transition A{sup 2}Σ{sup +}-X{sup 2}Π of N{sub 2}O{sup +} radical: 100-000, 000-001, and 001-001

In this article three vibrational bands of the electronic transition A{sup 2}Σ{sup +}-X{sup 2}Π of the N{sub 2}O{sup +} radical (100-000, 000-001, and 001-001) are analysed through high resolution Fourier transform spectroscopy. The N{sub 2}O{sup +} radical was produced by Penning ionization of N{sub 2}O by colliding with metastable atoms of He(2{sup 3}S) in a reaction chamber. The spectra was recorded in a spectral range of 24 500–30 000 cm{sup −1} and obtained from 200 coadded interferograms recorded at an apodized resolution of 0.08 cm{sup −1}. Through a recursive way, the wavenumbers of the correspondent rotational transitions were reduced into molecular constants, improving the values previously reported. New values for the first vibrational energies ν{sub 1}{sup ′}, ν{sub 3}{sup ″}, and ν{sub 3}{sup ′} are also obtained and compared with previous values reported in the literature.
