The 12 pages that link to Hydrogen spectral series, each with the reason it gives.

• Selection ruleBroader topic: Selection rules determine which level-to-level lines appear in these series.

• Fine structureBroader topic: Their resolved lines reveal the small energy corrections predicted by fine-structure theory.

• Old quantum theoryRelated: The observed lines gave early quantum models a precise target for explanation.

• Rydberg formulaBroader topic: Fixing one principal quantum number in the formula produces a named spectral series.

• Balmer seriesNarrower topic: Balmer’s group is one member of the full set of hydrogen series.

• Lyman-alpha forestNarrower topic: The Lyman series supplies the ultraviolet transitions behind the forest.

• Rydberg constantBroader topic: Each series follows from the Rydberg formula with a different shared lower level.

• Electronic spectroscopyBroader topic: The series provide a canonical example of discrete electronic emission spectra.

• Johannes RydbergBroader topic: Their regular spacing supplied a clear example of the pattern Rydberg sought to describe.

• ProtiumRelated: Protium’s electronic transitions generate the familiar hydrogen spectral lines.

• Type II supernovaRelated: Hydrogen lines in the supernova spectrum provide the defining observational clue.

• Type Ib and Ic supernovaeRelated: The absence of hydrogen lines is the defining spectral feature shared by Types Ib and Ic.
