摘要: This work investigates the capability of time-dependent density functional response theory to describe excited state potential energy surfaces conjugated organic molecules. Applications linear polyenes, aromatic systems, and protonated Schiff base retinal demonstrate scope currently used exchange-correlation functionals as local, adiabatic approximations Kohn-Sham theory. The results are compared experimental ab initio data various kinds attain a critical analysis common problems concerning charge transfer long range (nondynamic) correlation effects. goes beyond local investigation electronic properties incorporates global view surfaces.
