HeI photoelectron spectra (UPS) of six isomeric dihydroxynaphthalenes were
recorded and analysed with the aid of open shell SCF-CI calculations for re
spective radical cations, by considering relative band intensities and by c
omparison with spectra of other naphthalenes. The influence of hydroxy subs
tituents on the electronic structure is discussed and so is the reliability
of quantum chemical calculations. (C) 2000 Elsevier Science B.V. All right
