Eight emission spectra of CO2 + N2 mixtures excited by dc discharge were recorded using a Fourier Transform Spectrometer (Bruker Spectrometer 120HR) with a resolution of 0.003 cm-1 in the 4.5-µm region. Results (wavenumbers, band centers, spectroscopic constants) concerning 13 new vibrational transitions which have not been observed earlier and which occur between highly excited levels (hence their very small population) are reported. The derived spectroscopic parameters allow the reproduction of the experimental wavenumbers with a RMS < 3 x 10(-4) cm-1. Copyright 1998 Academic Press.

4.5-μm 区域的 12C16O2in 发射：Transitionsv1vl2v3→v1vl2(v3−1) with (2v1+v2) = 6 在高度激发的振动状态之间发生

使用傅立叶变换光谱仪（Bruker Spectrometer 120HR）在 4.5 µm 区域内分辨率为 0.003 cm-1 记录了由直流放电激发的 CO2 + N2 混合物的八个发射光谱。报告了关于 13 种新的振动跃迁的结果（波数、带中心、光谱常数），这些跃迁以前没有被观察到，并且发生在高激发能级之间（因此它们的种群非常小）。派生的光谱参数允许以 RMS < 3 x 10(-4) cm-1 再现实验波数。版权所有 1998 学术出版社。
