用高分辨率紫外-可见光傅里叶变换光谱仪记录了有无辅助微波激励的格里姆型辉光放电源的光谱。使用了各种阴极(铜、铝、铁和铬)，并以Ar或Ne为载气。直接记录真实的线条轮廓，便于研究线条形状。即使在相对强度发生重大变化的情况下，也可以明确地区分接近的线和进行识别。本文利用对大量谱线的相对强度测量，给出了激发条件对铁和铬光谱的影响的信息。结果强调，从有限数量的线上的数据推导出的任何“激发温度”都是没有意义的。详细讨论了电荷交换过程对离子谱线激发的贡献。线路轮廓测量将在随后的论文中报告。
A high-resolution ultraviolet–visible Fourier transform spectrometer has been used to record spectra from a Grimm-type glow discharge source with and without supplementary microwave excitation. Various cathodes were used (copper, aluminium, iron and chromium) with argon or neon as the carrier gas. True line profiles were recorded directly, so that line shapes could be studied easily. Close lines could be distinguished and identifications made unambiguously, even when major changes in relative intensities occurred. In this paper, information is presented on the effects of the excitation conditions on the iron and chromium spectra, using relative intensity measurements on a very large number of spectral lines. The results emphasize that any ‘excitation temperatures’ deduced from data on a limited number of lines are meaningless. The contribution of charge exchange processes to the excitation of ionic lines is discussed in detail. Line profile measurements will be reported in a subsequent paper.
