    • note
    • 2 was desorbed in a rapid anneal-and-quench thermal cycle, and the surface was imaged at room temperature. The rapid method minimizes the time available for the DBs to unpair, resulting in a population of predominantly paired DBs.

    • In an earlier halogen study [J. J. Boland, Science 262, 1703 (1993)], we noted that at room temperature, two Cl atoms that were bonded on neighboring dimers showed a distinct preference to be on the same side of the dimer row. This preference remained even under imaging conditions where single Cl atoms (and unpaired DBs) readily hopped back and forth between sites on the same dimer.

    • note
    • A preliminary analysis of hopping rates to determine the relative energies of paired and unpaired configurations indicated that the predissociated configuration is stabilized compared with that of unpaired DBs, although not to the extent of paired DBs.
