摘要：

He* (2(3)S) Penning ionization electron spectra (PIES) and He I ultraviolet photoelectron spectra (UPS) of some chlorotoluene derivatives, 2,4- and 3,4-dichlorotoluenes and 2,3,6- and 2,4,5-trichlorotoluenes, were measured. All the bands in the UPS were assigned on the basis of the characteristics of PIES and the results of ab initio molecular orbital (MO) calculations. The relative band intensities in the PIES strongly depend on the number of substituent Cl atoms and their positions relative to the methyl group. This effect was interpreted in terms of the spatial distribution of molecular orbitals.
