Transcript of Dissecting the Hirshfeld Surface

, 2023
The Hirshfeld surface was introduced by Spackman and Byrom in 1997, based on the Hirshfeld partitioning scheme for electronic contribution in molecular crystals. The Hirshfeld surface analysis and its fingerprint have become since then popular tools for visualization of intermolecular interactions and crystal packing.
