对含有不同浓度氮缺陷的辐照金刚石进行了光吸收测量。结果分析表明，单取代氮中心捕获空位的效率约为取代氮对的八倍。在低杂质含量的辐照金刚石晶体中，以及在合成金刚石膜中，观察到未记录的红外光谱，并归因于本征缺陷。
Optical absorption measurements were performed on irradiated diamonds containing different concentrations of nitrogen defects. Analysis of the results suggests that the single substitutional nitrogen centres trap vacancies about eight times more efficiently than the substitutional nitrogen pairs. In irradiated diamond crystals with a low impurity content, as well as in synthetic diamond films, an undocumented IR spectrum is observed and ascribed to intrinsic defects.
