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.
在本文中,通过高分辨率傅里叶变换光谱对N2O(+)自由基的电子跃迁A(2)Σ(+)-X(2)Π的三个振动带(100-000、000-001和001-001)进行了分析。N2O(+)自由基是在反应室中通过N2O与He(2(3)S)亚稳原子碰撞的彭宁电离产生的。光谱记录在24,500-30,000 cm(-1)的光谱范围内,由以0.08 cm(-1)的变迹分辨率记录的200个叠加干涉图获得。通过递归方法,将相应转动跃迁的波数简化为分子常数,改进了先前报道的值。还获得了第一振动能量ν₁'、ν₃"和ν₃'的新值,并与文献中先前报道的值进行了比较。
