Photoconductivity of nonpolar liquids induced by vacuum-ultraviolet light

Abstract
The intrinsic photoconductivity (pc) of 11 liquid hydrocarbons and silanes induced by VUV light was measured. From the onset of the pc the following thresholds were estimated in eV at T=(294±2) K: isopentane 9.15; n-pentane 9.1; neohexane 8.75; 3-methyl pentane 8.85; cyclohexane 8.75; n-tridecane 9.25; n-pentene-1 8.33; cyclopentene 7.4; tetramethylethylene 6.8; hexamethyldisilane 6.75; triethylsilane 8.25. Absolute quantum yields were determines at 120 nm for a field strength of 2.5 kV cm−1.
