Rydberg series formula

Rydberg series formula

[′rid‚bərg ¦sir·ēz ‚fȯr·myə·lə]
(spectroscopy)
An empirical formula for the wave numbers of various lines of certain spectral series such as neutral hydrogen and alkali metals; it states that the wave number of the n th member of the series is λ-R /(n + a)2, where λis the series limit, R is the Rydberg constant of the atom, and a is an empirical constant.
