Re: Pink Plasma

Here is a link to spectral data.  The .txt files are more informative
if you know how to translate Angstroms to a color band.

Nitrogen is predominantly in the blue (violet) region.  Our
ion implantors at work primarily use Nitrogen with a power
arc discharge through it to produce a plasma and it is
always blue/violet in color.  Hydrogen is predominantly in
the upper red region and Oxygen (the 2nd component of
water) is rather broad band (white) so the red of hydrogen
with the white of oxygen = pink ??? Just a guess as to where
the pink is coming from
