Abstract: Under ordinary conditions, azobenzene exists mainly as transisomer, and its photoisomerism is well known. In this work, We determined the quantum yield of this isomerization reaction by using simulative kinetic model on computer. We suggested a kinetic equation for azobenzene isomerization as
E=E_∞-Aexp(-Bt~σ)
In which, E and E_∞ are the absorbance of the azobenzene solution under radiation and photostatic state respectively, t is the radiation time A, B, C are emperical parameters. The kinetic equation can be solved by computer with a program written by ourselves, the values obtained were fitted to the practical data well.
