前言:本文主要介绍过渡态、反应路径的计算方法,并讨论相关问题。由于这类算法极
多,可以互相组合,限于精力不可能面面俱到展开,所以只介绍常用,或者实用价值有
限但有启发性的方法。文中图片来自相关文献,做了一定修改。由于本文作为帖子发布
,文中无法插入复杂公式,故文中尽量将公式转化为文字描述并加以解释,这样必然不
如公式形式严谨,而且过于复杂的公式只能略过,但我想这样做的好处是更易把握方法
的梗概,有兴趣可以进一步阅读原文了解细节。对于Gaussian中可以实现的方法,文中
对其在Gaussian中的使用进行了一些讨论,希望能纠正一些网上流传的误区。虽然绝大
多数人不专门研究计算方法,其中很多方法也不会用到,但多了解一下对开阔思路是很

度俯冲入海。
出事狮航这架班机属于波音737 MAX 8机型,先前就数度出现左右两侧攻角传感器感应
有误,导致数据错误;此外,飞机失事后,多位该机型驾驶也表示事前并不清楚这款机
型安装了新型安全系统“机动特性增强系统,暂译”(Maneuvering Characteristics
Augmentation System,M.C.A.S.),因此当然不清楚... 阅读全帖 |
