用dmol算了一个体系,HOMO-LUMO gap很大,我说这个结构化学性质比较稳定,而且文献上这样的说法也很多。但审稿人这么讲“the HOMO-LUMO gap is not an indication of the chemical stability. It is an approximation of the hardness of the system. They could use this data to discuss about the convenience of these materials for the construction of solar cells”。我该怎么回答呢?
