## Abstract A tentative assignment is proposed for the He (I__a__) photoelectron (PE.) spectra of the title compounds. It is based on the assumption that the first four π‐bands occupy the same position in both spectra, as suggested by a qualitative correlation with the PE. spectrum of [2~4~](1,2,4,
## Abstract Ultravoilet photoelectron spectroscopy has been employed to exmamin the valence electronic structure of 5‐fluorouracil, 5‐chlorouracil, 5‐bromouracil, and 5‐iodouracil. Photoelectron bands associted with the three highest π orbitals and the two oxygen atom lone‐pair orbitals were assign
