Article

Seventy-six diamonds with detectable C centers were selected based on the presence of a 1344 and/or 2688 cm–1 absorption in their infrared (IR) spectra. Such diamonds are always distinctly colored, often in yellow to orange with various modifications of colours such as brown and green. Fifty-seven of them had an IR spectrum exhibiting the well-known C center-related 1344.4 cm–1 (hereinafter 1344 cm–1) IR absorption peak with an absorption coefficient of more than 0.1. The IR spectra of 15 diamonds had a 1344 cm–1 peak with an absorption coefficient below 0.1 cm–1. Finally, in the spectra of 4 samples the 1344 cm–1 peak was undetectable because of strong aggregated nitrogen absorption but the 2688 cm–1 line was present. When the 1344 cm–1 absorption is superior to 0.1 cm–1, this fairly sharp line (FWHM = 3.3–4.2 cm–1) at 2688 cm–1 is detected, which correlates in intensity with the 1344 cm–1 feature.
