Computational Chemistry is a field that utilizes computer simulations and theoretical methods to investigate chemical phenomena. It involves applying mathematical models and algorithms to study the structure, properties, and behavior of molecules and materials at atomic and molecular levels. Computational chemistry plays a crucial role in predicting molecular interactions, designing new compounds, optimizing reaction pathways, and understanding complex chemical systems. It integrates principles from physics, chemistry, mathematics, and computer science to provide insights into chemical processes that are challenging to study experimentally.
