We have developed an experimental set up which combines an in vacuum liquid jet with a soft x-ray emission spectrometer to enable resonant inelastic soft x-ray scattering (RIXS) measurements from liquids. RIXS is a powerful technique which enables to probe occupied and unoccupied electronic states with elemental and chemical selectivity. Advantages of using a liquid jet are continuous replenishment of the sample and absence of membranes to separate the liquid from the vacuum. These properties make the setup suitable for complementary usage at synchrotrons and x-ray free electron laser facilities. As example, RIXS L-edge spectra of K3[Fe(CN)6] and CrCl3 aqueous solutions together with K-edge spectra of bulk water and alcohols are presented. These measurements were done at the BESSYII synchrotron radiation facility in Berlin, Germany.
