.. _drug_design_images: ************ Drug-design ************ Small organic crystals ---------------------- Predicting the stability of molecular crystals remains a formidable challenge in the natural sciences. We perform pairwise EFP calculations on crystal lattices in a periodic box, with the aim of developing a computationally tractable scheme involving EFP and quantum mechanical methods like SAPT to aid crystal structure predictions.
