Deriving Elastic Parameters From Lattice Vibrations In Copper (Ii) Acetylacetonate

Terahertz frequency vibrations exhibit characteristics that can be related to mechanical elastic parameters and yield insight into bulk physical properties. Through a combination of experimental low-frequency spectroscopy and solid-state density functional theory, specific vibrations can be used to determine elastic moduli. Applying this technique to a small metal-organic system, copper (11) acetylacetonate, provides new understanding of its unusual elastic behavior.
