Abstract: In this paper the principle of the azobenzene actinometer for the determination of light intensity was discussed. The method can also be used to determine the quantum yield of a photochemical isomerization of A<﹦>B type. A computer program was designed to calculate the data relevant to the determination of light intensity and quantum yield.

Key words: Photochemical Isomerization, Actinometer Cis-Trans Isomerization
