Molecular Physics is a branch of physics that focuses on the behavior and interactions of molecules. It studies how molecules form, their structures, and how they interact with each other and with energy. This field combines principles from both quantum mechanics and thermodynamics to understand phenomena at the molecular level. Researchers in molecular physics explore various topics, including chemical bonding, spectroscopy, and molecular dynamics. By examining these aspects, scientists can gain insights into processes such as chemical reactions, phase transitions, and the properties of materials. This knowledge is essential for advancements in fields like materials science and biophysics.
