This document includes description of the BLYP-D2 optimized structures of the adsorption systems of nitrogen containing compounds (NCCs, 2,4,6-trinitrotoluene (TNT), 2,4-dinitrotoluene (DNT), 2,4-dinitroanisole (DNAN), and 3-nitro-1,2,4-triazol-5-one (NTO)) in a parallel and perpendicular orientation toward the octahedral and tetrahedral kaolinite surface. We will use the following notations in the text, Tables, and Figures for presented kaolinite systems: K(o)-TNT(=), K(o)-DNAN(=), K(o)-NTO(=), K(o)-DNT(=), K(t)-TNT(=), K(t)-DNAN(=), K(t)-NTO(=), and K(t)-DNT(=) for the systems with the adsorbate in a parallel orientation toward the kaolinite surface and K(o)-TNT(), K(o)-DNAN(), K(o)-NTO(), K(o)-DNT(), K(t)-TNT(), K(t)-DNAN(), K(t)-NTO(), and K(t)-DNT() for the systems with the adsorbate in a perpendicular orientation toward the kaolinite surface. First experimental T∆Sads [kcal/mol] values for various adsorption systems are presented in Table S1 with the list of references on the bottom of this file. Tables S2-S5 present low vibrational frequencies [cm-1] and T∆Sads [kcal/mol] values calculated at the BLYP-D2 and M06-2X-D3(Cluster) levels for adsorption of nitrogen containing compounds (NCCs) in a parallel orientation toward the tetrahedral (K(t)) and octahedral (K(o)) kaolinite surfaces from the gas phase (K-NCCs(=)). Figures S1-S6 illustrate the optimized structures of TNT, DNT, and DNAN adsorbed in a perpendicular orientation on the octahedral and tetrahedral surface of kaolinite (K-NCCs()).
