Effect of stacking disorder on the Raman spectra of diamond exhibiting cubic-hexagonal features in their stacking pattern. (a) Calculated Raman spectra along the random stacking line and (b) along the line of constant 50% hexagonality. (c) Comparison of experimental Raman spectra of Popigai and cubic diamonds with corresponding calculated spectra of similar hexagonalities. The calculated spectra in part (c) have been downshifted by 10 cm−1 to allow direct comparison with the experimentally measured Raman shifts.
