This dataset contains (TD-)DFT calculations (Gaussian 09 output files) for a series of 2,7-fluorene bridged triarylamine dimers in their neutral-, monoradicalic- and diradicalic state. The dataset is used in a print publication from the Lambert group with the title “Tuning Electron Transfer Coupling and Exchange Interaction in Bis-triarylamine Radical Cations and Dications by Bridge Electron Density”. For the detailed content list, please refer to the read me file.
