用透射校正电子能谱仪测量了CO/sub 2/ HCHO、CH/sub 3/CHO、CH/sub 3/CH/sub 2/CHO、HCOOH、CH/sub 3/COOH和CH/sub 3/CH/sub 2/COOH的He 2/sup 3/S Penning电离电子能谱和He I光电子能谱。在从头算分子轨道计算的基础上，分析了PIES中的相对带强度。结果发现，一个isolobal类比持有的亲电攻击后，亚稳氦原子的目标分子轨道的相对反应性。参考文献31篇，图9幅，表2张。
He*(2/sup 3/S) Penning ionization electron spectra (PIES) and He I photoelectron spectra of CO/sub 2/ HCHO, CH/sub 3/CHO, CH/sub 3/CH/sub 2/CHO, HCOOH, CH/sub 3/COOH, and CH/sub 3/CH/sub 2/COOH were measured with a transmission-corrected electron spectrometer. The relative band intensities in PIES were analyzed on the basis of ab initio MO calculations. It is found that an isolobal analogy holds for the relative reactivity of target molecular orbitals upon electrophilic attacks by metastable helium atoms. 31 references, 9 figures, 2 tables.
