The spectra that you observe are for approximately 1 x 1012 atoms. So it is likely, that with electronic excitation, many of the electronic energy levels will be readily populated. However, the higher energy levels will be less populated, so what does say about the intensity of the higher energy peaks? Is that observation consistent with the spectrum we measured with the spectrometer?
