Cu-Fe的Slater-Koster参数（如下图所示，在CuFeO2的结构中，并没有发现Cu-Cu bond，Cu-Fe bond)？
The mean absolute error for the binding energy per hydrogen bond computed with our parameters is 4.29 kcal/mol. The suggestion for improving the performance of our parameters is based on including in the reference data the energy profiles for all possible intermolecular motions in water dimer.范...

The conference area proper was a short walk from the campsite and based in a large bedouin tent with surprisingly good acoustics. The intimacy of us sitting under the canvas together helped foster a bond. We all sat and chatted with our neighbours, no matter what nationality or speciality. A...
DFTB-optimized structures predicted using the trans3d parameters show a good agreement with both experimental crystal geometries and density functional theory (DFT)-optimized structures for Fe-N bond lengths. Conversely, Fe-C bond lengths are systematically overestimated. We improve the accuracy of Fe-...
Influence of ions on the hydrogen-bond structure in liquid water The orientational-correlation time of water molecules in ionic solutions has been measured with femtosecond pump–probe spectroscopy. It is found that the ... AW Omta,MF Kropman,S Woutersen,... - 《Science》 被引量: 951发表:...

Our results suggest that two dispersion correction models, D3(BJ) and D3(CSO), generally improve different properties including barrier heights, isomerization energies, bond dissociation energies, and non-covalent binding energies. The D3(CSO) model, with fewer dispersion coefficients and DFTB-...
