Lyman Series

(hydrogen series from electrons settling from n > 1 to n = 1)

The Lyman Series is Ultraviolet (UV) Spectral Lines of the Hydrogen (H) atom as an electron goes from State of Excitation n = 2 or greater down to n = 1. It is named after Theodore Lyman. (As opposed, for example, to the Balmer Series for n = 3 or greater down to n = 2.)

  • 2 -> 1: 121.6 nm (aka Lyman Alpha (Ly-α))
  • 3 -> 1: 102.6 nm
  • 4 -> 1: 97.3 nm
  • 5 -> 1: 95.0 nm
  • 6 -> 1: 93.8 nm
  • 7 -> 1: 93.1 nm
  • 8 -> 1: 92.6 nm
  • 9 -> 1: 92.3 nm
  • 10 -> 1: 92.1 nm
  • 11 -> 1: 91.9 nm
  • infinity -> 1: 91.18 nm

Rydberg formula:

1/Wavelength = RH ( 1 - 1 / n2 )

RH is the Rydberg Constant for hydrogen, 1.09737316 x 107m-1 = 13.6eV / hc
