The Lyman series corresponds to the emission lines of hydrogen atom due to the transitions of the type n → 1 ( 2 → 1 , 3 → 1 , 4 → 1 , etc ) where n is the principal quantum number of the excited state. The ionization energy of the hydrogen atom can be determined by plotting:

Frequency differences between successive emission lines vs emission frequencies

Frequency differences between successive emission lines vs n
