【摘要】 研究了四个三岔共轭系列（N_n,P_n,M_n,NE_n）的差示脉冲极谱.实验表明,对于三岔共轭化合物一般都呈现两个明显的还原峰;两个峰的峰电位都分别与同系因子（1/2）^2/N成良好的线性关系,相关系数大于0.95.同系列化合物的峰电位与HMO法计算之LUMO能级及电子吸收光谱波数之间有良好的线性关系;但不同系列化合物的峰电位与LUMO能级之间没有线性关系.更多还原

【Abstract】 In this paper the differential pulse polarographies of four bifurcate conjugate homologous series （N_n,P_n,M_n, NE_n） have been studied. It has been found that there are two clear reduction waves for these compounds. When the peak potentials are correlated with the homologous factor （1/2） ^2/N, it has been verified that there is a good linear relationship in every case. The correlation coefficients are greater than 0.95. There are also good linear relationships between the peak potential and the energy of LUMO calculated by HMO method, and between peak potential and wave number of electronic spectra for the homologous series. There is, however, no such linear relationship between the peak potential and LUMO energy for compounds of different series.更多还原
