Abstract
Complete double photoelectron spectra are presented for 18 small molecules where the location of charges in the cations and dications
is relatively clearly defined. The data demonstrate the importance of a coulombic repulsion contribution to the double ionisation energies. Examination of data for a wide range of molecules leads to a new empirical rule to calculate double ionisation energies from the
molecules’ single ionisation energies and maximum dimensions. Where single and double ionisation energies are known the rule allows
the deduction of plausible intercharge distances
