在氮放电的位置柱中，对氮的第二正系统的谱带进行了宽范围的强度测量。测量已被用来获得C3 π u态的振动能级的相对布居。计算出的激发概率检查一些可能的激发过程有助于这些人口。作为使用这些与测量相结合的结果，建议在正列中，填充C3 Pi u状态的主要过程是由电子从基态（x1 Sigma g）直接激发，其他过程所起的作用非常小。
Intensity measurements on bands of the second positive system of nitrogen have been made over a wide range of conditions in the position column of a nitrogen discharge. The measurements have been used to obtain relative population of the vibrational levels of the C3 Pi u state. Calculated excitation probabilities are examined for some of the possible excitation processes contributing to these populations. As a result of using these in conjunction with the measurements, it is suggested that in a positive column, the main process for populating the C3 Pi u state is direct excitation by electrons from the ground state (x1 Sigma g), the part played by other processes being very small.
