本人是gaussian計算新手,請大家?guī)兔纯磫栴}出在哪里!先謝謝了! 二價鈷離子和檸檬酸鹽(CoC6H5O7-)的絡合物,采用HF/Lanl2dz 方法進行結構優(yōu)化,計算出錯。輸入結構結構摘自有機晶體結構數(shù)據(jù)庫CCDC,刪掉了部分原子。 輸出Log文件報錯: The electronic state of the initial guess is 2-A. Requested convergence on RMS density matrix=1.00D-08 within 128 cycles. Requested convergence on MAX density matrix=1.00D-06. Requested convergence on energy=1.00D-06. No special actions if energy rises.

Restarting incremental Fock formation. Density matrix is not changing but DIIS error= 1.82D-06 CofLast= 6.60D-02. The SCF is confused.
