In this paper analyzing stationary structures of NH~+_(4)(H_(2)O)_(n)(n=1~6) clusters,it is found that the first stationary structure is linear hydrogen bonding NH~+_(4) with H_(2)O in clusters,the second is bifurcated structure,the third is trifurcated structure.
本论文分析了NH4+(H2O)n(n=1~6)簇合物的稳定结构,发现NH4+与H2O以线性氢键结合成的簇合物结构最稳定,其次是二叉结构,再次是三叉结构。
