Abstract
THE flash photolysis technique1 has been used to examine the photochemical decomposition of lead tetramethyl. At an energy of 2,500 joules (50 µF.; 10 kV.) the decomposition of lead tetramethyl at pressures up to 12 mm. mercury was shown to be largely complete in 1.2 m.sec. after the initial light flash; this was the time for the reaction vessel to become opaque to light due to the deposition of a lead film. The contents of the quartz reaction vessel (volume 500 cm.3, surface/volume = 1.6) were examined in this interval by passing a second light flash through the length (1 metre) of the vessel into a large Littrow (Hilger E1) spectrograph using a slit width of 0.02 mm.
