Abstract:Electrostatic interaction energies of water molecules, hydroxyl and ammonium ions occluded in AlPO4-15 molecular sieve are estimated from the modeling of the experimental X-ray charge density by numerical integration using a partitioning of the density based on multipolar pseudo-atoms.
Keywords:A. Microporous materials   C. X-ray diffraction
