2D-scan求助

根据一篇文章,我尝试用2D-scan扫描一个分子,计算的都失败了不知什么原因,请各位高手指教。 我的输入文件是: # opt(maxcyc=100,addredundant) upbe1pbe/6-31+g* scf=(qc,nosymm) geom=connectivity Title Card Required 0 1 C H 1 B1 H 1 B2 2 A1 H 1 B3 2 A2 3 D1 0 C 1 B4 2 A3 3 D2 0 C 5 B5 1 A4 2 D3 0 H 6 B6 5 A5 1 D4 0 H 6 B7 5 A6 1 D5 0 H 6 B8 5 A7 1 D6 0 O 5 B9 1 A8 6 D7 0 O 10 B10 5 A9 1 D8 0 H 11 B11 10 A10 5 D9 0 H 11 B12 10 A11 5 D10 0 B1 1.09041428 B2 1.09834559 B3 1.09588262 B4 1.50403959 B5 1.48882226 B6 1.08944121 B7 1.10029571 B8 1.09377481 B9 1.22943504 B10 2.25904576 B11 0.97274001 B12 0.97271156 A1 109.92873208 A2 111.12632155 A3 112.20520707 A4 120.67941448 A5 111.38556342 A6 106.61508768 A7 109.59825862 A8 115.77988206 A9 112.26541245 A10 97.56795174 A11 99.56438207 D1 -119.61623552 D2 118.83803220 D3 169.57863237 D4 161.78293646 D5 -79.13473791 D6 36.72209100 D7 -179.31990089 D8 -177.29025062 D9 129.69444934 D10 -123.23665237 1 2 1.0 3 1.0 4 1.0 5 1.0 2 3 4 5 6 1.0 10 2.0 6 7 1.0 8 1.0 9 1.0 7 8 9 10 11 12 1.0 13 1.0 12 13 7 11 2.33673 s 10 -0.153 7 10 2.5872 s 10 -0.178 输出文件显示的错误为: Iteration100 RMS(Cart)= 0.00002839 RMS(Int)= 0.03650170 New curvilinear step not converged.

我昨天收到高斯客服的邮件, Thank you for your inquiry. The error here indicates that the program was not able to make the modification of the structure to compute the next scan point without changing other internal coordinates. The redundant internal coordinates are very convenient but the drawback of having the redundancy in the internal coordinates is that this type of situations can happen, i.e. a change in one internal coordinate cannot be done without altering other internal coordinates and/or there are multiple solutions and the program cannot decide for the most appropriate one. What this means is that, unfortunately, in some cases, one needs to do scans in smaller sections or even computing some points in the scan separately. It sometimes helps using smaller step sizes, you may try for example scan steps of ~ 0.1 Angstrom (yours are > 0.15 Angstrom, which can be too long for certain geometries). Of course, that would also mean that you would need to compute more scan points than what you are doing here. By having somewhat smaller changes, there may be a smaller chance of failure when the program needs to generate the geometry of the next scan point. Sincerely, 但是如果按原先的方法的话,多加步数好像也不行 |
