The transient dynamics of carbon monoxide (CO) molecules on a Ru(0001) surface following femtosecond optical laser pump excitation has been studied by monitoring changes in the unoccupied electronic structure using an ultrafast X-ray free-electron laser (FEL) probe.

Infrared Spectrometer

A newly designed multichannel Fourier transform infrared spectrometer has been constructed for single-event time-resolved spectroscopy. It is capable of measuring unrepeatable transient events such as phase transitions, explosions, etc., with a time resolution of up to 5.14 ms. The mid-infrared region of 4500–2500 cm−1 is covered with a maximum spectral resolution of 13 cm−1. The developed system is used to measure the phase transitions of alkanes. The solid–solid and solid–liquid phase transitions of octadecane and nonadecane have been studied with time resolutions of 5–50 ms.

Elastic And Inelastic Scattering

The Elastic and Inelastic Scattering (EIS) beamline at the free-electron laser FERMI is presented. It consists of two separate end-stations: EIS-TIMEX, dedicated to ultrafast time-resolved studies of matter under extreme and metastable conditions, and EIS-TIMER, dedicated to time-resolved spectroscopy of mesoscopic dynamics in condensed matter. The scientific objectives are discussed and the instrument layout illustrated, together with the results from first exemplifying experiments.
