| Abstract |
|
A synthetic diamond with high 13C concentration was investigated by the use of Raman spectroscopy. The exact 13C concentration was determined from the position and width of the single band in the first-order spectrum using established relations between these values and the 13C content (Hass, K. C., et al. Phys. Rev. B 1992, 45, 7171-7182). The concepts of optical and acoustical phonons, first Brillouin zone, and dispersion curves are introduced to explain the appearance of the second-order Raman spectrum of 13C diamond. By using the criteria of energy and wave vector conservation in the Raman scattering process, it is shown how detailed information about band positions and intensities can be extracted directly from the dispersion curves, explaining the rather complicated spectrum in a conceptually easy way.
