Splet20. jul. 2007 · We report theoretical investigations of the tomographic procedure suggested by Itatani et al. [Nature (London) 432, 867 (2004)] for reconstructing highest occupied molecular orbitals (HOMOs) using high-order harmonic generation (HHG). Due to the limited range of harmonics from the plateau region, we found that even under the most … SpletA hybrid functional exchange-correlation PBE1PBE was chosen, which gave accurate results in the TD-DFT simulation of the metal–ligand complexes [51,52], including phthalocyanines . For computational cost reasons, we have limited our simulation to closed-shell systems such as porphyrins 3–5. The effect of a solvent (0DMF) on the energy of ...

SpletAbstract Several recent studies (J. Phys. Chem. A 2004, 108, 5479; J. Comput. Chem. 2007, 28, 2431) have shown impressive results when replacing the non-empirical PBE density functional by the empirical OPBE or OLYP functionals, ie replacing the PBE exchange functional by Handy and Cohen's OPTX functional.
