Improved molecular constants of the 000-000 band of the electronic transition A2Σ+-X2Π of N2O+ radical

Abstract

In this paper the 000-000 vibrational band of the electronic transition A(2)Σ(+)-X(2)Π of the N2O(+) radical is analyzed, 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 vacuum chamber. The spectrum 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. A total of 280 lines were adjusted to the model with a standard deviation of 0.006 cm(-1).
