Photoelectron spectroscopy and substituent effects in halonaphthalenes.
The electronic structure of two isomeric dibromonaphthalenes (C(10)H(6)Br(2)) has been investigated by HeI/HeII photoelectron spectroscopy. The spectra were assigned by Green's functions calculations and comparison with the spectra of related dibromobenzenes (C(6)H(4)Br(2)). The analysis of pi-orbital and halogen lone pair ionization energies, enabled us to determine the magnitude of bromine-bromine intramolecular interactions and distinguish between through-bond and through-space type interactions. We also discuss the halogen-halogen interactions in other polynuclear aromatics.
