The high repetition rate of LCLS-II combined with advanced instrumentation for time-resolved resonant inelastic X-ray scattering (RIXS) will map the energy distribution and evolution of occupied and unoccupied molecular orbitals of model complexes and functional photo-catalysts in liquid environments. Understanding the fundamental processes of photo-chemistry is essential for directed design of photo-catalytic systems for chemical transformation and solar energy conversion that are efficient, chemically selective, robust, and based on earth-abundant elements. The beamline will have two separate instruments with fixed interaction points – qRIXS and chemRIXS.  In the hutch the qRIXS endstation will be situated upstream, while the chemRIXS endstation will be located downstream.
