In order to get the photo-absorption spectrum over the full UV/vis region, more viable alternatives are thus developing around semiempirical approaches. The pristine tight-binding variant to LR-TDDFT (TD-DFTB) is one of them. Efforts are currently dedicated to its application to standard and more complex architectures such as dimer assemblies of noble metal nanorods. However, being prone to self-interaction and delocalization errors (SIE and DE, respectively) just like DFT in its semilocal exchange-correlation approximation, the approach strongly underestimates charge-transfer-like excitations. Since the latter strongly govern the absorption spectra of such extended and electronically delocalized system, 'ghost excitations' have to be carefully identified prior interpretations. The Visscher's alternative to TD-DFTB, is TD-DFT+TB. In short, the approach goes a step further by first fully solving the Kohn-Sham DFT equations and then treating the resulting guess with the linear-response formalism as implemented for TD-DFTB. By construction, TD-DFT+TB loses of course the computational efficiency of the pristine TD-DFTB.
