Recording time-resolved structures of complex molecules (such as protein complexes) by femtosecond X-ray pulses is among the important goals of ELI-Beamline’s project. However, these techniques are still in the process of being developed and suffer from a high level of damage that is inflicted on a sample. In contrast, time-resolved vibrational spectra can map molecular conformations in a highly non-invasive way. The possibility of running these experiments simultaneously with X-ray experiments would allow for valuable supplementary information to be obtained to cross-validate the conclusions drawn from the X-ray experiments. A crucial advantage of the stimulated Raman probe is the great flexibility it offers in terms of beam delivery, because it is based on pulses in the optical domain.
