FIG. 8.

Water gas and liquid phase photoelectron spectra taken with p-polarized 39.2 EUV photon energy and using the 900 gr/mm grating. For the liquid phase, the EUV beam is focused onto the bulk and contributions from the surrounding gas-phase molecules are also present. For recording the gas phase spectrum only, the liquid microjet was moved $\sim 40$ μm from the EUV focus away from the TOF entrance.
