The quantum yields of the photodecomposition of aniline and its derivatives in heptane, the formation of hydrogen, and the formation of aminyl radicals and their dependence on the excitation energy were determined. A table shows the intensity of light falling on the cell under measurement conditions, and a figure illustrates absorption of aniline in heptane, transmission of filter with Cl/sub 2/ for separation of the lambda= 254 nm line, transmission of the combination of UFS-5 and ZhS-20 filters for separation of the lambda=300 nm line, and absorption of the Aberchrome540 actinometer. It was concluded that cleavage of the N-H bond with the formation of H atoms and aminyl radicals is the only photochemical process in the irradiation of an ilines in heptane with light. The quantum yields were determined, and it was found that the quantum yields of photodissociation increase sharply with an increase in the excitation energy.
