This is a project to perform laboratory measurements and modeling to determine the predissociation rate of the c'(0)-x(0) transition in molecular nitrogen. The results will be used with a model to determine the temperature dependence of absorption oscillator strength, A-factors for radiative branching into the vibrational levels of ground state molecular nitrogen, and fractional predissociation. These data will facilitate an unambiguous identification of the rotationally resolved emission spectra of nitrogen and provide a basis for calculating, comparing and analyzing the absolute photoexcitation, photodissociation, electron impact excitation, and electron impact dissociation cross sections of nitrogen. This information will be useful in the interpretation of spectroscopic measurements of the upper atmosphere.

这是一个进行实验室测量和建模的项目，以确定分子氮中c '（0）-x（0）跃迁的预解离速率。 结果将被用来与一个模型，以确定吸收振子强度的温度依赖性，A-因子辐射分支到基态分子氮的振动水平，和分数预解离。 这些数据将有助于明确的识别氮的旋转分辨发射光谱，并提供了计算，比较和分析的绝对光激发，光解，电子碰撞激发，和电子碰撞解离截面的氮的基础。 这些信息将有助于解释高层大气的光谱测量。
