Quantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical systems, particularly towards the quantum-mechanical calculation of electronic contributions to physical and chemical properties of molecules, materials, and solutions at the atomic ...
Quantum Chemistry. In this unit, we describe how electrons are arranged in atoms and how the spatial arrangements of electrons are related to their energies. In the next unit, this will allow us to explain how the arrangement of electrons in an atom enables chemists to predict and explain the chemistry of an element.
8. Juni 2024 · Quantum chemistry applies quantum mechanics to the theoretical study of chemical systems. It aims, in principle, to solve the Schrödinger equation for the system under scrutiny; however, its ...
Quantum chemistry makes it possible to understand why certain compounds are stable, how molecules absorb and emit light, and even how drugs interact with biological systems. By solving the Schrödinger equation, quantum chemists can explain and even predict these properties.
28. Juni 2023 · This book helps readers grasp the essential quantum mechanical principles and results that serve as the foundation of modern chemistry and become knowledgeable in major methods of computational chemistry and spectroscopic experiments being conducted by present-day researchers.
