摘要: 本文用CNDO/2的量化计算方法估计了单硅酸、双硅酸和三硅酸分子中氢氧键的强度,并以此解释实验发现的这几种硅酸溶液的酸强度:单硅酸>双硅酸<三硅酸。

Abstract: The strength of O-Hbond in silicic acid from monomer to trimer has been investigated by using CNDO/2 method. The computed values give a reasonable explanation for the experimentally measured acid strength which is found to be.monomer >dimer<trimer.
