title: High resolution analysis of three bands of the electronic transition A²Σ⁺-X²Π of N₂O⁺ radical: 100-000, 000-001, and 001-001.
abstract: In this article three vibrational bands of the electronic transition A(2)Σ(+)-X(2)Π of the N2O(+) radical (100-000, 000-001, and 001-001) are analysed through high resolution Fourier transform spectroscopy. The N2O(+) radical was produced by Penning ionization of N2O by colliding with metastable atoms of He(2(3)S) in a reaction chamber. The spectra was recorded in a spectral range of 24,500-30,000 cm(-1) and obtained from 200 coadded interferograms recorded at an apodized resolution of 0.08 cm(-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 ν₁', ν₃", and ν₃' are also obtained and compared with previous values reported in the literature.
