The vibrational excitation of molecules by electrons in diffuse plasma, such as those found in cometary coma or used in industrial etching, is a key but poorly understood process. Excited vibrational states can either emit photons giving rise to tell-tale observable signature emissions or be a stepping-stone to further processes such as dissociation via further electron impacts

扩散等离子体中的电子对分子的振动激发，例如在彗星彗发中发现的或在工业蚀刻中使用的，是一个关键但知之甚少的过程。激发的振动态可以发射光子，从而产生可观察到的信号发射，或者成为进一步过程的垫脚石，例如通过进一步的电子碰撞进行解离
