Various time-resolved techniques have been developed to monitor the dynamics of reacting molecules, but most of the spectroscopic methods give only limited information on the molecular structure. Time-resolved X-ray Solution Scattering (TRXSS) has been developed by using the X-ray pulse, instead of optical pulse, as a probe and gives the time-resolved scattering response very sensitive to global molecular structure1-2. In this talk, three interesting applications of TRXSS1,3-4 will be presented. Reference [1] K. H. Kim, J. G. Kim, S. Nozawa, T. Sato, K. Y. Oang, T. W. Kim, H. Ki, J. Jo, S. Park, C. Song, T.
