Induced electron resonance?

[HMS-776]

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)

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!
