IR and X-ray time resolved simultaneous experiments: an opportunity to investigate the dynamics of complex systems and non-equilibrium phenomena using 3rd generation synchrotron radiation sources

"Third-generation storage rings are modern facilities working with high currents. and designed to host powerful radiation sources, like undulators and wigglers,. and to deliver high-brilliance beams to users. Many experiments at high spatial. resolution, such as spectromicroscopy at the nanometre scale and with high. temporal resolution to investigate kinetics down to the picosecond regime, are. now possible. The next frontier is certainly the combination of different methods. in a unique set-up with the ultimate available spatial and temporal resolutions.. In the last decade much synchrotron-based research has exploited the advantage. of complementary information provided by time-resolved X-ray techniques and. optical methods in the UV\/Vis and IR domains. New time-resolved and. concurrent approaches are necessary to characterize complex systems where. physical–chemical phenomena occur under the same experimental conditions,. for example to detect kinetic intermediates via complementary but independent. observations. In this contribution we present scientific cases from original works. and literature reviews to support the proposed IR\/X-ray simultaneous approach,. with both probes exploiting synchrotron radiation sources. In addition, simple. experimental layouts that may take advantage of the high brilliance and the. wide spectral distribution of the synchrotron radiation emission will be given for. specific researches or applications to investigate dynamic processes and nonequilibrium. phenomena occurring in many condensed matter and biological. systems, of great"
