In the thermodynamic context, the equilibrium constants for 𝐴𝑄(𝐶𝑂 2 ) 2 2-adduct formation for these isomers can be deduced by examining the difference in the oxidation peaks associated with the 𝐴𝑄 2-and 𝐴𝑄(𝐶𝑂 2 ) 2 2-redox reactions . The 𝐾 𝐴𝑄_𝑎𝑑𝑑𝑢𝑐𝑡 can be calculated with the following equation (derivation included in SI Section 2.2 and Figure ):
