%X The vibronic spectra mainly depend on the nature of the defects in diamond. The strong sharp local vibronic modes are observed for the interstitial-related centres beyond their phonon cut-off energy (165meV), but not for the vacancy-related centres. The vibronic spectra of these vacancy-related centres show very strong and broad sidebands closely after the zero phonon lines. Further, the vibrations involving only one vacancy are due to two separate phonons or both, one has an energy of approximately 42 meV and the other has approximately 67 meV.
