Phys Chem Chem Phys. 2016 Aug 03;18(31):21288-95. doi: 10.1039/c6cp02403c.

Quantum-mechanical calculations are performed to investigate the structural, electronic, and infrared (IR) and Raman spectroscopic features of one of the most common radiation-induced defects in diamond: the "dumb-bell" 〈100〉 split self-interstitial. A periodic super-cell approach is used in combination...
