To obtain satisfactory convergence for these systems would require several µs of simulation time. However, to show that including these lateral interactions would approach our results to the experimental ones, we have used a non-linear least squares fitting of Eq. ( ) to the experimental data, using the same values for the hard-disk area and the adsorption energy as before, while optimizing B (see Fig. ). The resulting MTT adsorption isotherms closely match the experimental data where B = 0.114 nm 2 for Jaishankar et al., B = -0.453 nm 2
