What Does HFI Stand For?

HFI stands for Hyperfine Interaction

HFI, or Hyperfine Interaction, refers to the subtle interactions between the magnetic moments of atomic nuclei and the surrounding electrons in an atom. This phenomenon plays a crucial role in various fields of physics and chemistry, influencing nuclear magnetic resonance (NMR) and electron spin resonance (ESR) techniques. HFI provides insights into the electronic structure of atoms and molecules, as well as their magnetic properties, and is essential for applications in materials science, quantum computing, and medical imaging.
