Computational Chemistry Literature Review
Computational chemistry is a rapidly growing field that uses computer simulations to study the properties and behavior of molecules and materials. This field has a wide range of applications, including drug discovery, materials science, and environmental chemistry.
Key Points:
- Computational chemistry is a powerful tool for studying the properties and behavior of molecules and materials.
- Computational chemistry can be used to predict the structure, reactivity, and properties of new compounds.
- Computational chemistry can be used to design new drugs, materials, and catalysts.
- Computational chemistry can be used to study the interactions between molecules and their environment.
Main Concepts:
Quantum mechanics: Computational chemistry is based on the principles of quantum mechanics, which describe the behavior of electrons and nuclei in molecules and materials.
Molecular mechanics: Molecular mechanics is a simpler approach to computational chemistry that uses classical physics to describe the interactions between atoms in molecules.
Density functional theory: Density functional theory (DFT) is a widely used method for computational chemistry that uses a simplified model of the electron density to calculate the properties of molecules and materials.
Ab initio methods: Ab initio methods are computational chemistry methods that do not rely on any approximations. These methods are the most accurate but also the most computationally expensive.
Molecular dynamics: Molecular dynamics is a computational chemistry method that simulates the motion of atoms and molecules in time. This method can be used to study the behavior of molecules in solution, at interfaces, and in biological systems.
Conclusion:
Computational chemistry is a powerful tool for studying the properties and behavior of molecules and materials. This field has a wide range of applications and is likely to continue to grow in importance in the future.
