The photolysis of liquid n-hexane has been studied at room temperature and at −78°C by using the resonance lines of Xe and Kr. The main process is hydrogen detachment, giving the same amount of hydrogen and of hexenes; relatively small amounts of the decomposition and dimer products were also formed. Upon the addition of SF6, the yield of the hydrogen detachment decreased strongly with an increase in the concentration of SF6, and then approached a constant value of 0.65 relative to that in pure n-hexane. The total amount of fluorinecontaining products detected in the presence of SF6 was relatively small compared with the amount of the decrease in the hydrogen detachment. As another electron scavenger, C6H13F was also tested; here, the decrease in the hydrogen detachment was quite small.
