摘要

利用N,2,常压弧光放电产生低能N,+,经电场加速后注入胞嘧啶（C）水溶液，研究了低能N,+,作用后胞嘧啶水溶液的pH值、紫外、红外及核磁共振光谱的变化。结果表明，溶液pH值由于N,+,的注入而逐渐下降，低能N,+,对溶液样品造成了多种形式的损伤，形成丰富多彩的损伤产物。其中不仅包括水溶液中多种损伤碎片之间的重新化合，还包括N,+,与溶液中元素形成新的化学基团，继而与其它碎片结合形成产物，使外来的N,+,“沉积”在溶液样品中。

Abstract

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.
