Abstract:

Nitrogen atom and molecule ions were generated in gas discharge near the surface of water. Effects of the ions on water were studied. The results showed that water exhibits remarkable UV absorption after the ions' impact, and has positive reaction with ninhydrin, which indicates that amine products are formed, and the observation of 1H-NMR spectrum further proves the existance of these products. The pH value of water lowred after discharge, and chemical analysis demonstrated NO3- produced in the sample solution, i. e. HNO3is another kind of substance formed in the reaction of ions with water as well. All the results give evidence of the chemical syntheses of low energy nitrogen ions with liquid water. And these synthesis effects may play a role in the chemical evolution of life.
