Induced electron resonance?

  1. Sep 15, 2009 #1
    Can someone please explain to me how resonance can be induced into the electrons of an atom using pulsed electrical fields?

    Can this also be done using photons of a specific wavelength?

    If by photons you mean a CW beam, then it should be able to excited an atom the same way a pulsed beam could. I'm assuming you're just referring to spectroscopy and not something exotic.

    Here is a copy of my post to another of your threads:

    Hi HMS-
    A very good example of this resonant absorption is the 3P-->3S sodium spectrum (the yellow doublet).
    If you look at the lines with a diffraction grating you will see the yellow doublet (wavelength about 5890 Angsroms)
    http://hyperphysics.phy-astr.gsu.edu...um/sodium.html [Broken]
    with about a 5 Angstrom splitting. Each of the two lines is broadened by the temperature of the sodium gas in the arc. If you look carefully, you will see a dark absorption line in the middle of each doublet line, caused by the emission lines being strongly resonantly absorbed by the surrounding colder sodium gas.

    Thanks again BOB S and everyone for the great help!
