If you have benzene, for example, the lowest electronic state, is quite far below the first excited state.
比如苯环，也就是最低电子态，远低于第一激发态。
The degenerate energy levels of the first excited state are not relieved. The degenerate energy levels of the second excited state are relieved partially.
第一激发态的简并没有消除，第二激发态的简并被部分地消除。
