【求助】请教各位大侠,做吸收光谱时不收敛 已有3人参与
|

我做吸收光谱时总出现Davidson failed to converge within maximum sub-space dimensions.,我都计算了有将近10天了,敬请各位大侠帮我支招,非常感谢.下面是我使用的方法 方法:#B3LYP/6-31G* TD(Triplets,NStates=10) Test 以下是部分输出文件: 40 initial guesses have been made. Convergence on wavefunction: 0.001000000000000 Iteration 1 Dimension 40 NMult 40 CISAX will form 40 AO SS matrices at one time.
