摘要： 本文在文献[1]的基础上,进一步研究了正烷烃CnH2n+2及其它19个非共轭体系的60组光电子能谱,发现它们的各级垂直电离势也符合同系能级线性规律或同系线性规律,但线性相关系数前者比后者更好一些。

Abstract: In the present investigation we have collected 60 sets of vertical ioniza-tion potentials of normal paraffins CnH2n+2 and other 19 sets of non-conjugated homologous series from UV photo electron spectroscopy and found to fit the following linear equation Ip(n,k)=a+bX(n,k) where IP(n, k) is the kth ionization potential of the nth member of the homologous series, a and b are constants, X(n,k)is called the homologous energy factor and is equal to X(n,k)=[(2k-1)/k]sin(kπ/(2n+1)] 83.3% of the correlations are of the "excellent" grades with correlation factor r≥0.99, and 16.7% of the "good" grade with r≥0.95.
