1. 总能看到HF和post-HF,都是啥意思呢?我常用的是B3LYP,也用过MP2。这些泛函都是如何来划分呢?
2. Multiwfn Manual中提到(P31),Multiwfn determines if atoms are bonded by empirical distance criteria, if the distance between two atoms is short than 1.15 times of the sum of their van der wals radii, they will be considered as bonded. 我想问的是:1.15这个值是怎么来的?约定俗成的吗?还是有文献可查呢?(这涉及到我前一段时间问您的关于M-sulfur成键的问题,如果直接通过键长和范德华半径的比较就可以初步判断是否成键,那就方便了好多呀!)另外,这里所说的那个范德华半径是不是在百度中查到的那些数值呢?还是在multiwfn中有这个范德华半径的数值呢?
3. 请问结构图的清晰度可以通过什么来调节呢?
3 “清晰度”这个词太含糊。如果你是指图像像素大小,用settings.ini里的参数调,手册有说明:
For curve maps, the height and weight of the picture are controlled by “graph1Dsize”
parameter in settings.ini, “graph2Dsize” is responsible for two-dimension data plotting (colorfilled
map, contour map, relief map, etc.), “graph3Dsize“ is responsible for three-dimension data
plotting (isosurface graph, molecular structure graph).
