Hi, Professor David:
sorry so late to reply you!
Recently, I have been doing the substitution Si atom by Al atom, and more, want to simulate the N2 adsorption in Al-substituted zeolites. And one more question on the extra-framework-molecule definition. In the pseudo_atom.def (Genericzeolites force-filed), I found the Na, Ca and Cl ions are with the same radii, namely, 1.0 A. And if I want use the K atoms as the extra framework molecule, the radii of K atom is set to 1.0 A ? if so, how to consider the effect of different radii on the adsorption behavior?
Thanks for your reply!
Best Wishes!
