Monitoring size growth by electrospray ionization mass spectrometry. Time-course electrospray ionization mass spectra of size growth reaction from [Au25(SR)18]− to [Au44(SR)26]2− in a low and b high m/z regime. For ease of identification, the starting cluster [Au25(SR)18]−, product cluster [Au44(SR)26]2−, as well as an important intermediate cluster [Au38(SR)24]0 are highlighted in magenta, blue, and olive, respectively. The detailed formula of Au(I)-SR complexes or cluster intermediates identified in mass spectrometry are listed in Table 1
