Feller, J. Comp. Chem., 1996, 17, 1571-1586; K. L. Schuchardt, B. T. Didier, T. Elsethagen, L. Sun, V. Gurumoorthi, J. Chase, J. Li, and T. L. Windus, J. Chem. Inf.

The total energy was corrected for entropic and thermal contributions and as shown as a free energy ΔG‡ in kcal/mol., relative to TS1 or {relative to reactants}. cAn OAI-PMH compliant institutional data repository, providing access to full information about each system, including the total calculated energies via Gaussian checkpoint and logfile files, coordinates are in CML form, and the metadata conforms to the METS specifications. dTFA = trifluoroacetate, OTf = trifluoromethanesulfonate.
