Request for Link on orbital decay energy characteristics

  1. May 7, 2012 #1
    While reading an older article by Schrodinger on Causality a question occurred to me about the nature of energy/time characteristics of light emitted by electron orbital decay.

    I have been thinking for some time on the relationship/contrasts between generation of lower frequency (ie radio) waves and light waves.

    Any links to good articles/information on quantum/wavelike nature of EM radiation produced by electron orbital decay would be appreciated

    The lowest frequency / longest wavelength emission line of hydrogen is the hyperfine structure line at 1420 MHz / 21 cm.
    See http://en.wikipedia.org/wiki/Hydrogen_line

    It is due to the coupling of the magnetic moments of the electron in the 1s atomic (ground) state and the proton.

    Thanks for the link on the hydrogen microwave line. Interesting; a small energy change resulting in a microwave frequency.

    I found this link previously and just realized that some of the information applies to my interest in visible light photon characterization.
