Now it worked, though not much to see for this example. 22 Potentially, real-time and nonadiabatic TDDFT can model both single and multiple. So, I think the square of that coefficient multiplied by 100 should give the percentage contribution of that. The RIJCOSX approximation becomes almost indispensable here and can make calculations that are almost impossibly expensive without the approximation, relatively straightforward with the approximation (see Figure 1 below). The bookkeeping of time ordering is naturally maintained in real (physical) time, allowing the formulation. cess is still debated. In Table 1, we give the values for the excitation energy and transition dipole moments obtained by the Gaussian fitting procedure of the dynamical polarizability tensor in the framework of P-TDDFT as implemented in the OCTOPUS package. being predominantly a periodic code, local. As TADF dyes typically consist of hundreds of atoms, time-dependent density functional theory (TDDFT) often is the only computationally viable approach still accurate enough for modelling TADF processes.
