This quiz is modified from a version originally made for Rowan's employees. The real functionals are derived from those suggested in the QChem manual. The fake ones were deliberately designed to baffle even the most seasoned DFT experts. To learn more about the various classes of DFT functionals, how they're constructed, and which ones Rowan recommends, check out our article on The "Charlotte's Web" of Density-Functional Theory (DFT).
