Epitope maps of the four pesticides dissolved in the pH7 buffer or D2O. The percentage values for each epitope map are all relative to the strongest binding proton in each pesticide, which is expressed as 100%. Protons which have 80–100% binding are highlighted by red circles, protons with 65–79% with blue, and 64% and lower with green. The shaded region in D1 and D2 simply highlights the side of the molecule that has the strongest interaction with the soil surface. An asterisk (*) indicates that absolute quantification was not possible at these positions due to spectral overlap.
