Abstract
An increasing number of studies take advantage of ion mobility spectrometry (IMS) coupled to mass spectrometry (IMS-MS) to investigate the spatial structure of gaseous ions. Synthetic polymers occupy a unique place in the field of IMS-MS. Indeed, due to their intrinsic dispersity, they offer a broad range of homologous ions with different lengths. To help rationalize experimental data, various theoretical approaches have been described. First, the study of trend lines is proposed to derive physicochemical and structural parameters. However, the evaluation of data fitting reflects the overall behavior of the ions without reflecting specific information on their conformation. Atomistic simulations constitute another approach that provide accurate information about the ion shape. The overall scope of this review is dedicated to the synergy between IMS-MS and theoretical approaches, including computational chemistry, demonstrating the essential role they play to fully understand/interpret IMS-MS data.

Abstract
Donepezil has polymorphism. Different crystalline forms can exhibit different physicochemical properties and biological activities. Exploration of intermolecular interactions is essential to reveal the formation mechanism and differences in properties of polymorphs. This study explores the weak non-covalent intermolecular interactions of donepezil polymorphs through fully ab initio quantum mechanical methods, semi-empirical methods, and Hirshfeld surface analysis. The results show that the Hirshfeld surface analysis method can clearly and intuitively reveal the intermolecular interactions. Theoretical calculations using the atom-atom Coulomb-London-Pauli (AA-CLP) method were also performed to understand the interaction energies toward the total lattice energy. The value of the lattice energy was in accordance with the melting points of the donepezil polymorphs and brought to light the nature of thermal stability. In the specific energy distribution, the contribution of the dispersion force is the most prominent. Further interaction energy analysis found that within a distance of 3.8 Å from the center of the donepezil molecule, different crystalline forms of donepezil molecules have different interaction energies with surrounding molecules. The different interaction energies between polymorphs may lead to polymorphs with different physical-chemical properties.
