Hydrogen emission spectrum

  1. Jun 9, 2009 #1
    I keep seeing the hydrogen emission spectrum from the Balman series (when an electron falls to n=2). It's all over my text book.
    Why don't I ever see the Lyman series or any other series?

    Is it really rare for hydrogen electrons to fall to energy levels other than n=2?

    Only the Balmer series is visible. The Lyman series is UV, and the Paschen series is IR. If you have a good spectrometer, compare hydrogen to the deuterium spectrum.

    It takes a very good spectrometer to distinguish hydrogen from deuterium. A decent Eschelle will do it, but the sort of thing you will find in a Chem 101 lab probably won't.

    I love the names...Lyman, Balmer,Paschen, Bracket,Pfund and Humphreys.We need one more to make the magnificent seven.How about Dilbert?
