The redox process of norepinephrine in pH=7.0 phosphate buffer solution at glassy carbon electrode was studied by circular dichroism spectroelectrochemistry with a long optical path thin layer cell. The spectroelectrochemical data were analyzed with the double logarithm method. According to the double logarithsmic plot results, the mechanism of electrochemical oxidation of norepinephrine is an irreversible process with a subsequent chemical reaction (EC) to form a norepinephrinechrome. Both of norepinephrinequinone and norepinephrinechrome are followed E mechanisms. Some kinetic parameters about the electrochemical process, i.e. the electron transfer coefficient and number of electron transfered, αn= 0.38, the formal potential, E 1 0' = 0.20 V, the standard heterogenous electron transfer rate constant, k 1 0=1.2×10 -4 cm•s -1 for the oxidation of norepinephrine, αn=0.37, E 2 0' =0.25 V and k 2 0 =4.4×10 -5 cm•s -1 for the reduction of norepinephrinequnone and αn=0.33, E 3 0' =-0.25V and k 3 0=1.1×10 -4 cm•s -1 for the reduction of norpinephrinechrome, were also estimated.
