The formation of gold nanoparticles in the presence of dodecanethiol was observed in situ by quick X-ray absorption fine structure spectroscopy with 100 ms time resolution at the Au L-3 and L-2 edges. The series of the X-ray absorption near edge structure spectra at both edges was analyzed to evaluate the dispersion and electronic properties of gold nanoparticles during their growth.
