Abstract
High temperature–high pressure annealing experiments on diamond transform type IB dispersed nitrogen into type IA aggregate nitrogen. The activation energy for the transformation is approximately 60 kcal mol−l (2.6 eV). An estimate is given for the diffusivity of nitrogen in diamond for this transformation
