Computational chemistry plays a crucial role in the process of drug discovery. By simulating interactions between potential drug candidates and target proteins, computational chemists can identify promising compounds that have the potential to become effective drugs. This approach saves time and resources by narrowing down the pool of compounds for experimental testing.

2. Material Science

Researchers in the field of material science rely on computational chemistry to explore the properties of materials at the atomic and molecular level. Understanding these properties helps in the development of new materials with enhanced properties, such as strength, flexibility, conductivity, and more.

3. Catalysis

Catalysts are substances that facilitate chemical reactions without being consumed in the process. Computational chemistry aids in designing and optimizing catalysts by modeling how they interact with reactant molecules and studying the reaction mechanisms. This knowledge helps in developing more efficient and sustainable catalytic processes for various industrial applications.

The Tools of Computational Chemistry

Computational chemists employ a wide range of tools and software to carry out their research. These tools can be broadly classified into two categories: quantum chemistry and molecular mechanics.

1. Quantum Chemistry

Quantum chemistry focuses on solving the Schrödinger equation, which describes the behavior of electrons in atoms and molecules. Various methods, such as Hartree-Fock (HF), density functional theory (DFT), and coupled cluster theory (CC), are used to approximate the electronic structure and energy of molecules. Quantum chemistry calculations are computationally demanding and require high-performance computers.

2. Molecular Mechanics

Molecular mechanics approximates the behavior of molecules by treating them as collections of interacting atoms. Force fields are used to describe the potential energy of molecules, allowing the determination of their structures and properties. Molecular mechanics calculations are less computationally intensive compared to quantum chemistry and are suitable for larger systems.

Challenges and Future Directions

While computational chemistry has revolutionized the field of drug discovery and materials science, it still faces several challenges. One major challenge is accurately modeling the intricacies of biological systems, such as proteins and enzymes, due to their size and complexity. These systems require more advanced computational techniques and models to achieve reliable results.

The future of computational chemistry holds great promise. New algorithms and techniques are continuously being developed to improve the accuracy and efficiency of simulations. Additionally, advancements in computer hardware, such as quantum computers, have the potential to revolutionize computational chemistry even further.

Practical Aspects of Computational Chemistry I: An Overview of the Last Two Decades and Current Trends gathers the advances made within the last 20 years by well-known experts in the area of theoretical and computational chemistry and physics. The title itself reflects the celebration of the twentieth anniversary of the “Conference on Current Trends in Computational Chemistry (CCTCC)” to which all authors have participated and contributed to its success.

This volume poses (and answers) important questions of interest to the computational chemistry community and beyond. What is the historical background of the “Structural Chemistry”? Is there any way to avoid the problem of intruder state in the multi-reference formulation? What is the recent progress on multi-reference coupled cluster theory? Starting with a historical account of structural chemistry, the book focuses on the recent advances made in promising theories such as many body Brillouin-Wigner theory, multireference state-specific coupled cluster theory, relativistic effect in chemistry, linear and nonlinear optical properties of molecules, solution to Kohn-Sham problem, electronic structure of solid state materials, development of model core potential, quantum Monte Carlo method, nano and molecular electronics, dynamics of photodimerization and excited states, intermolecular interactions, hydrogen bonding and non-hydrogen bonding interactions, conformational flexibility, metal cations in zeolite catalyst and interaction of nucleic acid bases with minerals.

Practical Aspects of Computational Chemistry I: An Overview of the Last Two Decades and Current Trends is aimed at theoretical and computational chemists, physical chemists, materials scientists, and particularly those who are eager to apply computational chemistry methods to problem of chemical and physical importance. This book will provide valuable information to undergraduate, graduate, and PhD students as well as to established researchers.
