计算S－T激发时，在out文件中，显示T1的跃迁耦极矩的地方，有可能出现这个warning：

这个报错可以忽略。理论来源参考：F. Wang and T. Ziegler, A simplified relativistic time-dependent density-functional theory formalism for the calculations of excitation energies including spin-orbit coupling effect, Journal of Chemical Physics 123, 154102 (2005)中方程22、23。
