WebOct 24, 2014 · The top trace is calculated using a Czjzek distribution of the central transition only with δiso = 100 ± 5 ppm and CQ = 6.5 ± 0.5 MHz. Even without calculations, these NMR results point toward P 6 3 / mmc (194) as the correct space group, since there is no experimental evidence of the second Mg 2+ site required by P 6 3mc (186).
