Photoconductivity measurements of X-ray absorption fine structures (XAFS) at the Si and Cl K-edge have been carried out in a liquid cell for (CH{sub 3}){sub 4},Si [(CH{sub 3}){sub 3}Si]{sub 4}Si and eitheras a pure liquid or 2,2,4-trimethylpentane solution. It is found that for the pure liquids and their concentrated hydrocarbon solutions, all K-edge XAFS spectra are inverted as expected under the condition of total absorption. A sharp conductivity dip is also observed in CCl{sub 4} at the Cl K-edge. The concentration dependence of the XAFS spectrum of CCl{sub 4} is reported. These results are discussed in terms of soft X-ray induced ion yields of the solute and solvent molecules in liquids.
