For each set of C-H sites in a molecule, we determine the minimum hydricity (Δ𝐺 • 𝑚𝑖𝑛 ). Hereafter, we assume a linear relationship between the experimental hydricity and Δ𝐺 • 𝑚𝑖𝑛 , as this assumption allows us to derive the empirical constants a and b and correct any systematic errors, such as the hydride (H -) ion; see Equation , where Δ𝐺 • is replaced by Δ𝐺 • 𝑚𝑖𝑛 . After retrieving the empirical constants a and b, we can now determine the QM computed hydricities for all C-H sites using Equation .
