体系是非共轭结构,先对基态进行优化后,对0 1做stable=opt,得到稳定的基态波函数。
继续读取chk文件进行激发态优化。
#p opt td=(nstates=10) wb97xd def2svp geom=check guess=read
第一激发态的能量太低了,第二激发态正常。homo-lumo是378-379
Excited State 1: Singlet-A 0.3380 eV 3668.23 nm f=0.0001 <S**2>=0.000
371 -> 379 0.10210
372 -> 379 -0.10155
378 -> 379 -0.67144
This state for optimization and/or second-order correction.
Total Energy, E(TD-HF/TD-DFT) = -5363.05943346
Copying the excited state density for this state as the 1-particle RhoCI density.
