To fit the log tranforms of oxidative or reductive two-electron waves adjusting 0, 1 or 2 values of k2/k0. The equations used are described and explained in ref. [11,12]. You should first remove a polynomial baseline from the catalytic wave, Dirk's method, and then take the log transform using the logt command. The current equations are:

for a reductive wave (

(7) |

for an oxidative wave (

Use `lo20` or `lr20` if you believe that electron transfer is
so fast with respect to turnover that the wave is reversible (from an
electrochemistry point of view). (This corresponds to fixing both
apparent k2/k0 values to zero.)

Use `lo21` or `lr21` if this is not the case, but if you want
to assume that both apparent k2/k0 have the same value.

Note that measuring the maximal slopes of the log-transforms should help you deciding whether electron transfer is fast or not [12].

If you use `lo22` or `lr22`, both apparent k2/k0 values are
adjusted.
