用电子能量损失谱法获得了氨在5.5-11 eV能量范围内的单重激发态的新数据。在4° ~ 40°的散射角范围内，对50 eV激发谱进行了高能量分辨率（15 meV）的分析。一些已知的振动级数已经被具有高量子数v '的新的附加项所补充。五个最低能量单重态的微分截面已被测量在50 eV的冲击能量作为散射角的函数。这些数据导致讨论Rydberg系列的分类。
New data have been obtained about the singlet excited states of ammonia in the 5.5–11 eV energy range by electron energy loss spectroscopy. The 50 eV excitation spectrum has been analyzed with high energy resolution (15 meV) at several scattering angles ranging from 4° to 40°. Some known vibrational progressions have been completed by new additional terms with high quantum numbers v’. The differential cross section for the five lowest energy singlet states have been measured at 50 eV impact energy as a function of the scattering angle. These data lead to discuss the classification of the Rydberg series.
