Ab-initio prediction of the melting point of organic solids

The melting point is one of the most fundamental and practically important properties of a compound. For this reason molecular simulation methods have been developed aiming towards accurate computation of melting points. Knowledge of the melting point before a compound has been synthesized could significantly accelerate the design of new materials. Generally, the molecular simulation methods de...

Ab Initio Predictions of Structures and Densities of Energetic Solids

We have applied a powerful simulation methodology known as ab initio crystal prediction to assess the ability of a generalized model of CHNO intermolecular interactions to predict accurately crystal structures and densities of various classes of explosives. 174 crystals whose molecules contain functional groups common to CHNO energetic materials were subjected to this methodology and include ac...

Embedding Fragment ab Initio Model Potentials in CASSCF/CASPT2 Calculations of Doped Solids: Implementation and Applications.

In this article, we present a fragment model potential approach for the description of the crystalline environment as an extension of the use of embedding ab initio model potentials (AIMPs). The biggest limitation of the embedding AIMP method is the spherical nature of its model potentials. This poses problems as soon as the method is applied to crystals containing strongly covalently bonded st...

Ab initio random structure searching of organic molecular solids: assessment and validation against experimental data

This paper explores the capability of using the DFT-D ab initio random structure searching (AIRSS) method to generate crystal structures of organic molecular materials, focusing on a system (m-aminobenzoic acid; m-ABA) that is known from experimental studies to exhibit abundant polymorphism. Within the structural constraints selected for the AIRSS calculations (specifically, centrosymmetric str...
