100 ps time‐resolved X‐ray solution‐scattering capabilities have been developed using multilayer optics at the beamline NW14A, Photon Factory Advanced Ring, KEK. X‐ray pulses with an energy bandwidth of Δ E / E = 1–5% are generated by reflecting X‐ray pulses (Δ E / E = 15%) through multilayer optics, made of W/B 4 C or depth‐graded Ru/C on silicon substrate. This tailor‐made wide‐bandwidth X‐ray pulse provides high‐quality solution‐scattering data for obtaining photo‐induced molecular reaction dynamics. The time‐resolved solution scattering of CH 2 I 2 in methanol is demonstrated as a typical example.
