老师们好,请教各位老师几个问题,我有片小文章审稿人提了几点问题,不是很懂还望各位老师能帮忙解决下。文章主要算的共轭分子自聚机理实验用了NCI方法,但是由于初始堆积方式比较多,我就先用packmol产生了初始结构,然后跑了下MD,现在审稿人的问题是 I.3 The idea of using MD simulations to obtain dimer configurations for subsequent optimization is a decent one. However, many crucial details on the procedure are missing. For example, all the MD simulation details (force-field, time step ...). If only a single dimer configuration was eventually taken for the analysis what was the point of MD sampling? 这个问题除了补充具体细节,还要怎么回答,我使用packmol和MD就是想得到堆积能量最低的结构,然后再用orca计算,也不知道这样的想法对不对。还有一个问题是为了考察溶剂效应,我使用了screening model (COSMO),但是审稿人说 Simulation in two implicit solvent environments with very close (and low!) polarities such as toluene and n-Heptane cannot reproduce the experimental solubility. Explicit all atom MD (perhaps, even with a polarizable force-field) could be of use here. One would naively expect that toluene should compete for the stacking interactions in contrast to n-Heptane. 这个我用的量化计算审稿人说simulation,还有就是量化的隐形溶剂模型是不是本身就有缺陷,如果有这个问题有该如何回答
还望各位老师不惜赐教啊。 |
