Hi, if you have in mind the heterogeneous electron transfer rate constant, I think it is still quite good to use the old Nicholson approach (R.S. Nicholson, Anal. Chem. 37 (1965) 1351. Alternatively, you can make a simulation on your data (e.g. by good old electrochemistry simulations package - http://lem.ch.unito.it/chemistry/esp_manual.html).
Hello Dear Jan Hrbac , I was looking for something similar to the software that you have mentioned. I was looking at the link, where it says that I have to give input of
[Ox] [Red] [n e-] [E] [Ke] [alpha] , where I can see the peaks from the final figure I get from experiment. but how I will give the [n e-] [E] [Ke] [alpha], as I am not a very confident about CV theoretically. Will you please let me know how to find [n e-] [E] [Ke] [alpha] from the CV figure?
