Atomic Molecular and Chemical Physics (AMC)

Section Information

Atomic, Molecular and Chemical Physics focuses on the fundamental properties, interactions, and dynamics of atoms, molecules, ions, and chemical systems. It examines quantum structure, spectroscopy, reaction mechanisms, and collisional processes that govern matter at microscopic scales.

Modern research in this field includes quantum chemistry, ultrafast dynamics, laser–matter interactions, cold and ultracold atoms, molecular collisions, reaction kinetics, chemical physics of gases and condensed phases, and high-resolution spectroscopy. Advances in lasers, synchrotron and free-electron laser sources, computational modeling, and precision measurement continue to expand understanding of atomic and molecular behavior.

This section publishes theoretical and computational studies, experimental investigations, spectroscopic analyses, reaction-dynamics research, and methodological developments that deepen knowledge of atomic and molecular systems and support applications in physics, chemistry, materials science, and energy.
