    • This intermolecular potential was calculated as E(x, z) = E(naphthalene or pyrene/hydrogen molecule) - E(naphthalene or pyrene) - E(hydrogen molecule). Calculated energy for naphthalene was -384.61465476981 Ha and -384.73786470882 Ha at the MP-2/6-31G* and MP-2/6-311G* level, respectively. For pyrene, the energy was -613.78733125643 Ha at the MP-2/6-31G* level, and for the hydrogen molecule, the value was -1.1441408483251 Ha at MP-2/6-31G*, and -1.1458815873186 Ha at MP-2/6-311G*.

    • In the numerical calculations where the load is less than ∼0.1 nN, the distance between naphthalene and hydrogen is in the range of 2.30-2.94 Å located in the region around the minimum of the interbody potentials (the minimum is at ∼2.9 Å, see Figure 3).
