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.
