Low energy N,+, ions were produced by gas arc discharge and the ions were accelerated into cytosine (C) aqueous solution. Changes in pH, UV, FT—IR and ,1,H—NMR spectra of C solution after this kind of ions'action were investigated. It was showed that pH of the solution decreased with N,+, implantation,N,+, caused various damages on C molecules and many new substances were founded. These new substances were synthesized not only by combination of the damage fragments in the solution, but also by "deposition" of N,+, from outside.
