I suspect that because the atoms are equal, the charge oscillates back and forth across the molecule. >I also need info on how to ionize air and what typical ionization levels >are. The degree of ionization can be determined with the Saha equation (http://en.wikipedia.org/wiki/Saha_equation) as Fred Sparber has pointed out many times. :) Ionization energies of specific types of molecules can be found at: http://webbook.nist.gov/chemistry/form-ser.html.en-us.en > >One thing I would like to include is radiation from currents in air due to >many molecules oscillating together. i don't know how to do this right now. Even within an air current, oscillations will still have random phase and direction, so I don't think air currents are going to make any difference. (Besides, the velocity of an air current is trivial relative to the velocities of individual molecules). >As far as I know from gas dynamics it is very rare for many molecules close >to each other to move in the same direction.
