Owing to developments in computer power and algorithmic efficiencies, quantum chemical methods have become essential tools for both fundamental scientific research and industrial problem solving. Quantum mechanics is routinely used in multiple industries including pharmaceuticals, polymers, specialty chemical production, and even national defense. Knowledge of reaction pathways and material properties are essential for improving and developing new materials and processes.

This presentation will showcase the application of density functional theory in combination with the growing string method, a novel reaction pathway finding technique, to elucidate the cationic polymerization mechanism of polyisobutylene. Additionally, the role of defects on the decomposition of chemical warfare agent simulants in Zr-based metal organic framework will be discussed. Lastly, a formalism for accurate estimation of dipole moment using quantum mechanics for complex molecules having conformational degrees of freedom and its application for estimating thermal physical properties will be presented.
