We also performed GCMC simulations of pure-component ethane and ethylene adsorption in the framework (Figure ). Although the simulations predict the experimental data much less closely than the model over the full dataset, in this instance, the simulation results are in closer alignment with experiment, with an expected ethane uptake of 3.08 mmol/g. In addition to the previously identified discrepancies between the approximate ML model and experiment where linkers are expected to be trapped in a pore, natural experimental variation 79 may also be a source of error.
