The structure of the defect responsible for the H1a absorption feature in diamond has been much debated. In this work, the results of uniaxial stress-splitting studies are compared to piezospectroscopic stress-splitting parameters calculated for the < 001 > dinitrogen split interstitial < N-2I > defect. The stress-splitting data shows that the H1a absorption band arises from an A -> E transition at a center with D-2d symmetry. Furthermore, the experimentally and theoretically determined stress-splitting parameters are in excellent agreement, supporting the assignment of the H1a band to the N-2I defect.
