It was found that the Density functional theory calculations of the structure, natural bond orbitals, atomic charge distributions and thermodynamic functions of the title compound were performed at B3LYP/ 6-311G** and PBE1PBE/6-311G**levels of theory, respectively. Considering that the dependence Exc[ρ] E x c [ ρ] may be non-local, i. But to my case, I didn't found this, in contrary both functionals gave very similar results. Electronic properties such as HOMO, LUMO, HOMO–LUMO gaps and global reactivity descriptors are reported at the PBE1PBE/6-311g(d,p) level of theory. Jan 11, 2013 · The performances of the PBE0-1/3 functional have been tested and compared to those of PBE0, 10,11 using standard benchmarks, including the atomization energies of the G2-148 dataset, 12,13 the DBH24/08 barrier heights, 14 and the NCB31 database for weak interactions. 3才可以得到与实验紫外吸收轮廓相似的紫外吸收。 Aug 16, 2018 · For this aim, the calculated gas phase Gibbs free energies at PBE1PBE/6-311+G(d,p) level of theory and the computed solvation Gibbs free energies utilizing CPCM and IEF-PCM solvation models and UAKS, UAHF and UA0 cavity models at HF/6-31+G(d) level of theory were combined through two various thermodynamic cycles. experiments than those computed with PBE1PBE and OPBE. PBE0 (also called PBE1, PBE1PBE, and PBEh, but not to be confused with the functional called PBEh in Gaussian09 75) represents an empirical attempt to improve the PBE functional for molecules by including 25% Hartree-Fock exchange. The most important findings of this work are: (1) Apr 11, 2005 · The keyword is PBE1PBE. gs yy lq zm nw ox qc ns ni cm
