In physics, the Paschen series (also called Ritz-Paschen series) is the series of transitions and resulting emission lines of the hydrogen atom as an electron goes from n ≥ 4 to n = 3, where n refers to the principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 4 to n = 3 is called Paschen-alpha, 5 to 3 is Paschen-beta, 6 to 3 is Paschen-gamma, etc.
Additional recommended knowledge
They are named after the Austro-German physicist Friedrich Paschen who first observed them in 1908.
Paschen series, in the infrared, measured lines with wavelengths (nm):
