Zip file containing optimised structures for each level of theory (AM1, AM1-IEFPCM, PM6, PM6-IEFPCM, UFF, wB97XD, wB97XD-IEFPCM). With the exception of IEFPCM folders, each level of theory includes the nucleophile (nuc), 1037 Michael acceptors (gs), and 1037 Michael addition transition states for the reaction of the nucleophile with each Michael acceptor (ts), complete with IEFPCM(toluene) single point energy calculations. IEFPCM folders include only the 37 literature reactions.
