Exploring the mechanism of proton motion coupled to a charge-transfer reaction in a new HBO derivative in solution using steady-state and ultrafast emission spectroscopy shows an abnormal spectroscopic and dynamical behavior.

The results of short time galvanostatic polarization experiments are described in which the maximum potential excursion is limited to ± 10 mV about the equilibrium potential.Exchange currents have been evaluated both geometrically and iteratively. The charge transfer reaction [Formula: see text]is slow. The dependence of the exchange current on the concentration of Pb(II) is consistent with a charge transfer coefficient of 0.2 in agreement with the arithmetical analysis of current–potential data.There is evidence for an adsorbed layer of hydrogen ion at the electrode.
