Figure 2From: Controlled reduction for size selective synthesis of thiolate-protected gold nanoclusters Aun(n = 20, 24, 39, 40)ESI-MS spectra of the new nanolcusters. (A ) Unsmoothed spectrum in the range of m/z 8,000 to 14,000 (inset, isotope pattern of m/z 11,793) and (B) zoom-in spectrum (smoothed).Back to article page
