A flash photolysis technique is useful to study chemical reactions of explosively burning hydrocarbon/oxidizer mixtures associated with emission and absorption spectra observations. When a single ion probe is inserted into the reacting gases to measure the ion current. it is positively or negatively electrified for a moment according to the conditions at the beginning of chemical reactions. A vacuum ultra-violet light (VUV) appears together with the CH, OH and C_2 spectra and causes a photoelectric effect not only on the probe surface but also on the inner surface of the quartz combustion tube. The positive or negative electrification can be derived theoretically from the photoelectric effect on the quartz tube. It is concluded that the emitter is highly excited carbon monoxide, because the VUV photon should have an energy higher than 10 eV to cause electron emission from the quartz tube inner surface.
