Following geometry optimization, TDDFT
(nroots = 16) was used for the sake of calculating the electronic excited states.
The prediction involves the MN12SX density functional beginning with the HOMO-LUMO gap instead of TDDFT
The long-term goal is to deliver an all-out theoretical and computational toolbox for QED-TDDFT applicable to complex molecular systems (like presently approachable by DFT and by TDDFT
The DFT and the TDDFT
calculations were performed with the TURBOMOLE  suite of programs using orbital basis sets of split valence [SVP]: [4s3p1d]  in the case of Si.
The absorption and fluorescence spectra, frontier molecular orbital, energy gaps, electronic structures, and MEP of Tetrabromophenol blue and Bromoxylenol blue are computed via DFT and TDDFT
--The maximums UV-Vis absorption spectra, obtained by TDDFT
calculations, are in the range of 748-511 nm, suggest that our designed compounds must absorb and convert the sunlight to electricity.
Objective: "The aim of this project (MODENADYNA) is to push Time-Dependent Density Functional Theory (TDDFT
) beyond the present ~state of the art~ by implementing a novel computational scheme to MODel Electron Non-Adiabatic DYNAmics due to electron-electron scattering processes.
The absorption spectra have been computed by using time dependent density functional theory (TDDFT
) at TD-B3LYP/6-31G level of theory.
In this work, theoretical study by using density functional theory (DFT) and time-dependent (TDDFT
) methods on eight small conjugated compounds based on terthiophene end-capped by several electron donor groups (-H, -CH3, -O-CH3, phenyl, fluorinyl, furanyl, thiophenyl and thienylenevinylenyl).
In this study, a cyanidin, which belongs to flavonoids, based new organic dye is modeled and its suitability as a novel sensitizer in DSSC is computationally tested using density functional theory (DFT) and time-dependent density functional theory (TDDFT
For a unified description of excitonic and charge transfer states we will combine constrained density functional theory (CDFT) and linear response time-resolved density functional theory (TDDFT
) within the configuration interaction framework.
