Abstract: Simultaneous measurement methods for soft X‐ray absorption spectroscopy (XAS) of solid–liquid interfaces and bulk liquids have been developed. The O K‐edge XAS spectra of H2O/Au interfaces and bulk H2O were measured using a transmission‐type liquid cell, in which the liquid layer was sandwiched between Au/Cr/Si3N4 and Si3N4 membranes. The XAS spectrum of bulk H2O was obtained using the transmission method by controlling the thickness of the liquid layer, whereas the XAS spectrum of the H2O/Au interface was obtained using the electron‐yield method by measuring the drain currents from the Au surface after soft X‐ray absorption. The XAS spectra of bulk H2O and the H2O/Au interfaces were differentiated to determine the appropriate measurement conditions for the solid–liquid interfaces interfaces. [ABSTRACT FROM AUTHOR]
