摘　　要：In this paper,the electric absorption spectra of axial coordination of Zn[Val-TPP] with imidazole was inverstigated.Coordination number and equilibrium constants of axial coordination reaction were measured by visible spectra techniques.The changes of standard molar enthapy Δ rH o m and standard molar entropy Δ rS o m of reaction were obtained from the plot of lnK vs 1/T. The experimental results showed that both Δ rH o m and Δ rS o m of coordination reaction were negative values.In this paper,the electric absorption spectra of axial coordination of Zn[Val-TPP] with imidazole was inverstigated.Coordination number and equilibrium constants of axial coordination reaction were measured by visible spectra techniques.The changes of standard molar enthapy Δ rH o m and standard molar entropy Δ rS o m of reaction were obtained from the plot of lnK vs 1/T.
