No so!!! These are changes of the plasma on a temporary and molecular=20 level. The pressure is different! In femto seconds (fS) or less, the=20 electrons displaced by the infusion of power drop back into their places=20 on other molecules that have recently had an electron torn from it=20 orderly orbit....and the process continues as long as power is applied. Try to tune plasma with an rf generator-plasma also acts as a diode! If you were to quantify the photonic output of the plasma and compare it=20 to the input power that created it, you would find that they are equal. GL.
