    • The failure of TD-DFT for the description of CT is considered to originate from an inadequate asymptotic behavior of the XC-potential (A. Dreuw, M. Head-Gordon, J. Am. Chem. Soc. 2004, 126, 4007-4016). The computed CT transitions in the present work, however, exhibit almost vanishing oscillator strenghths and therefore have little effect onto the interpretation of the calculated UV/Vis spectra of aryl-substituted thiazole-2(3H)-thiones.
