摘要

We report the results of multifrequency electron paramagnetic resonance studies at temperatures between 8 and 300 K on diamonds synthesized by chemical vapor deposition and intentionally silicon doped with isotopes in natural abundance or isotopically enriched. The ~(29)Si hyperfine structure has provided definitive evidence for the involvement of silicon in two electron paramagnetic resonance centers in diamond that were previously suspected to involve silicon: KUL1 and KUL3. We present data that unambiguously identify KUL1 as an 5= 1 neutral silicon split-vacancy (D_(3d) symmetry) defect (V-Si-V)~0, while KUL3 is shown to be (V-Si-V)~0 decorated with a hydrogen atom, (V-Si-V:H)~0.
