分子结构是何种态($T_1$?$S_0$?$S_1$?$T_1$)的优化结构,则out文件中,仅该态相关辐射跃迁数据有效,例如:
注意,激发态数目实际上是吸收峰的数目,但是计算的时候,是从最长波区域往短波区域计算。因此,激发态数目影响到短波区域的峰数量、峰形。数目本身不太影响计算效率,但是对内存需求剧烈增加,一般较大的分子无法计算超过100个激发态,否则对内存的需求将达到T的量级。

SCM - Spectra
列表中每一行,对应吸收峰的一个峰,点击将显示该吸收峰的来源,例如上图,表示该吸收峰是8a轨道跃迁到9a轨道。可以通过SCM - level查看能级图对照得到,实际上就是HOMO跃迁到LUMO。
