The He I photoelectron spectra of tetramethylcyclopentane‐1,2,3‐trione 1 , 4,4,6,6‐tetramethylcyclohexane‐1,2,3‐trione 2 , bicyclo[1.2.3]octane‐2,3,4‐trione 3 , bicyclo[2.2.3]nonane‐2,3,4‐trione 4 and anhydrous ninhydrine 5 are presented. The assignment of the first two bands is discussed using semiempirical calculations together with a qualitative band shape analysis. It is shown that the first two bands in 1 to 4 are due to the ionization of an electron from lone pair combinations of the 2 p ‐oxygen orbitals.
