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/sup 0/ to 40/sup 0/. 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.
