怎么用hyperchem畫結(jié)構(gòu)優(yōu)化的分子3D圖

The calculations carried out in this study were based on the use of MM+ Molecular Mechanics force field, with a Polak-Ribiere algorithm having a con- vergence limit 0.01 kcal mol− 1, performed on a Pentium IV personal computer with Hyperchem version 7.0 . The structure of the free ligand was optimized using the 6-31G* basis set at the restricted Hartree-Fock (RHF) level of theory. The optimized structure of the ligand was then used to find out the initial structure of its lanthanide complex. Finally, the structure of the resulting 1:1 complex was optimized at the semiempirical PM3 [24] level of theory employ- ing the restricted Hartree-Fock (RHF). |
