In the predominantly ECE case of trans-Mn(CO)2(ƞ 2 -DPPE)2 + in THF, the evolution of y vector as n increases illustrates how more definitive mechanism determination in edge cases will benefit from cyclic voltammograms of multiple v values (Fig. and). With additional voltammograms, the ErCr component in yielded y vector decreases from 0.73 (n = 1) to 0.12 (n = 5) while the ECE one increases from 0.27 (n = 1) to 0.88 (n = 5) (Fig. ). Such changes in y components as a function of n is consistent with the reported challenges in differentiating ErCr and ECE/DISP1 mechanisms with a small number of v. The output y vector from the DL model can be utilized to provide additional semi-quantitative analysis in addition to its function of designating the most probable mechanism. We propose that non-zero probabilities/fractions for mechanisms other than the most probable/prominent one suggest either a competing reaction or a gradual transition from one mechanism to another. In the one-electron reduction of Co II (TPP) in the presence of n-BuBr (Fig. ), the forward Cr step, namely the nucleophilic attack of Co I (TPP) •-towards n-BuBr, is pseudo-first-order on the concentration of n-BuBr ([n-BuBr]) and the forward rate constant kf is proportional to [n-BuBr]. The corresponding dimensionless kinetic parameter λ, proportional to kf/v (Fig. ), measures the competition between the solution reaction and redox specie's diffusion from/to the electrode surface. As [n-BuBr] increases or v decreases, λ is larger and leads to more pronounced "irreversibility" from the Cr step in the voltammograms. Experimentally, we found that the cyclic voltammograms display a smaller tendency of reoxidation of Co I (TPP) •-when [n-BuBr] increases from 10 mM (Fig. and) to 50 mM (Fig. and), and when the range of v values decreases from v ∈ [0.1, 1.0] V/s (Fig. and) to v ∈ [0.05, 0.7] V/s (Fig. and). Accordingly, as shown in Fig. , the ErCr component in the yielded y vectors gradually increased from 0.22 for Fig. to 0.86 for Fig. , while the component for Er correspondingly decreases from 0.78 to 0.14.
