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).
本文通过高分辨率傅里叶变换光谱分析了 N2O(+)自由基的电子跃迁 A(2)Σ(+)-X(2)Π的 000-000 振动带。N2O(+)自由基是通过 N2O 与 He(2(3)S)亚稳态原子碰撞的彭宁电离产生的。光谱记录在 24500-30000 cm(-1)的光谱范围内，由 200 个加和的干涉图记录，分辨率为 0.08 cm(-1)。通过递归方法，将相应的转动跃迁的波数降低到分子常数。总共 280 条线与标准偏差为 0.006 cm(-1)的模型相匹配。
