“…To investigate the reaction dynamics and structures of reaction intermediates, and subtle effects of atomic substitution, the molecular structures of reacting molecules must be characterized. In this regard, time-resolved X-ray liquidography (TRXL), also known as time-resolved X-ray solution scattering, is an excellent technique because it can be used to both provide global reaction pathways of chemical reactions and reveal the structures of transient intermediates in the liquid solution phase [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 ]. Thus far, TRXL has been used for studying the structural dynamics of a wide variety of systems spanning diatomic molecules, organometallic complexes, proteins, and nanoparticles in the solution phase [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 51 , 52 ...…”
