   newsgroup sci.astro.research, so I've set the "Followup-To" header   
   to point there.  Please conduct any further discussion in this thread

   about astronomical spectral-line physics) than here.

   Question:  Is the spectral line signal for hydrogen different for   
   hydrogen in hydrogen gas compared with hydrogen in water?   
      
   Or, if one where observing the spectral line for some distant   
   collection of hydrogen gas and then that gas reacted with some   
   sudden supply of oxygen forming water, would or does the spectral   
   signal change?   
      
   Thanks, in advance.
