用Dmol計(jì)算頻率,但結(jié)果沒有頻率
|

用Dmol計(jì)算頻率,輸入文件里有 # Calculated properties <-- Frequency_analysis on <-- _____________________________>8 但結(jié)果沒有頻率,以下是部分輸出文件,求幫忙 +++ Entering Vibrations Section +++ Message: Entering vibrations section Harmonic frequencies will be computed by finite differences.

樓主,你能把你的輸出文件貼出來嗎? 如果計(jì)算頻率,結(jié)果應(yīng)該會(huì)有的。 如: Symmetry analysis for vibrations:C1 symdec file generated by DMol freq a cm-1 % 378.5 100. 446.5 100. 1064.4 100. 1662.4 100. |

輸入文件是 # Task parameters Calculate optimize Opt_energy_convergence 1.0000e-005 Opt_gradient_convergence 2.0000e-003 A Opt_displacement_convergence 5.0000e-003 A Opt_iterations 500 Opt_max_displacement 0.3000 A Symmetry off # Electronic parameters Spin_polarization unrestricted Charge 0 Basis dnp Pseudopotential dspp Functional pbe Aux_density octupole Integration_grid medium Occupation thermal 0.0050 Cutoff_Global 3.7000 angstrom Scf_density_convergence 1.0000e-006 Scf_charge_mixing 0.2000 Scf_spin_mixing 0.5000 Scf_iterations 500 Scf_diis 6 pulay # Print options Print eigval_last_it # Calculated properties Frequency_analysis on |
