以HMO法剖析了二质子四苯基卟啉(H_2TPP~(2+))及其衍生物的紫外-可见光谱,确定了四苯基卟啉(TPP)和H_2TPP~(2+)及其衍生物的λ_(max)、pK_a与取代基常数σ间的线性关系。
The UV-Vis spectra of DTPA (HTPP 2+) and its derivatives were analyzed by HMO method. The results showed that TPP, HTPP 2+ and their derivatives Λ_ (max), pK_a and substituent constant σ between the linear relationship.
