    • p,c peak, the term reversible is applied; similarly, quasireversiblity refers to situations in which chemical reversibility is dependent on scan rate (i.e., reversibility is observed only at higher scan rates).

    • That this species is cationic is supported by the highly anodic reduction potential (-0.1 V) and its insolubility in hexane (in contrast to 1Hc and 1Ho) on extraction of the electrolysed solution.

    • Zhang et al. have also claimed that ring opening occurs when R = Me, Ph (1Fc), but no data were presented, and the time dependence of the oxidation of the closed form and formation of the open form were not examined. The present study confirms their observation of ring opening.
