Splet01. avg. 2010 · AbstractThe electronic absorption spectra of 29 phenyl-ring substituted chalcones have been investigated with the time-dependent density functional theory (TD-DFT) and polarizable continuum TD-DFT (PCM-TD-DFT). It turns out that the hybrid PBE1PBE functional with the 6-31G basis set provide reliable λmax when the solvent … 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 ...
