Quick Summary

Superhyperfine structure is a phenomenon observed in electron-spin resonance (ESR) spectroscopy. It occurs when the electronic magnetization of a magnetic center interacts with the magnetic moments of nuclei in neighboring atoms. This interaction causes each component of the fine-structure resonance spectrum to split further, creating what are known as hyperfine components. If the electronic magnetization is spread across multiple atoms, it can interact with more than one nucleus, leading to additional splitting known as superhyperfine structure. This effect provides detailed information about the electronic magnetization and helps test models describing defects in matter.1
