Lyman series




Lyman, Balmer, and Paschen series
The series of lines in the hydrogen spectrum associated with transitions to or from the first energy level or ground state. It lies in the ultraviolet (Lyman-alpha at 1215.67 ; Lyman-beta at 1026 ) with a series limit is at 912 . The He II Lyman lines have almost exactly one-quarter the wavelength of their hydrogen equivalent (He II Lyman-beta, 303.78 ; He II Lyman limit, 227 .)
