In this study, micro-Raman microscopy was used to examine graphite mechanical behavior through the evolution of dislocation defect density and the resultant deformation (strain) in graphite components. The increasing strength of the Raman optical phonon modes linked with a generous number of dislocations indicates the potential capability of Raman spectroscopy to help develop a mechanistic understanding of the complex mechanical behavior of graphite for use in many industries and applications.

Aromatic esters follow the ester Rule of Three, but each of these three peak positions is different for saturated and aromatic esters, which makes them easy to distinguish. Organic carbonates are structurally similar to esters and follow their own Rule of Three.
