    • In the Winstein formalism, ion pairs may be intimate or solvent separated. Our results do not allow us to make this distinction; therefore, we refer to them simply as ion pairs.

    • Other buffers used in MurA THI breakdown could potentially have similarly affected the product distribution, but the smooth transitions between different buffers and the fact that different buffers at a given pH gave the same product distribution argue against this.
