Powder optical absorption spectra of various tetrathiotetracene (TTT) salts are reported together with solution spectra of neutral and ionized TTT and TTT dimers. Intramolecular transitions are identified by comparing the solid state and solution spectra. The Coulomb correlation energy corresponding to charge fluctuation to TTT is 0.7 eV, independent of stoichiometry and of solid state properties. Complex TTT salts have a low lying optical excitation due to a transition between ionized and neutral molecules.
