Pfund series
From Wikipedia, the free encyclopedia
In physics, the Pfund series is a series of absorption or emission lines of atomic hydrogen. The lines were experimentally discovered in 1924 by August Herman Pfund, and correspond to the electron jumping between the fifth and higher energy levels of the hydrogen atom.
The wavelengths for consecutive transitions are:
- 7460 nm for the transition to n=6
- 4650 nm for the transition to n=7
- 3740 nm for the transition to n=8
- 3300 nm for the transition to n=9
- 3040 nm for the transition to n=10
- 2280 nm for the transition to n=
