    • Quantitative reaction efficiencies as a function of collision energy and collision gas pressure were also recorded; over the range of conditions examined, the isotope effects and product branching ratios did not change appreciably, although the overall reaction efficiency, i.e., yield, increased monotonically with increasing collision energy.

    • The error bound on the isotope effect is computed for 95% certainty and comes from 30 independent measurements.

    • The error bounds on the branching ratio is computed for 95% certainty and comes from 50 independent measurements. The branching ratios were also constant over the range of collision energies studied, i.e., nominally -2 to 14 eV in the laboratory frame.

    • In Scheme 2, the structures should not be understood to mean that we have assigned a particular stereochemistry to the five-coordinate intermediates. The structures are presumed to undergo facile pseudorotation. The present experiments make no prediction concerning the stereochemistry.
