Abstract
A series of oxonium and carboxonium ions and their corresponding proto nated dications were investigated by ab initio/IGLO/GIAO-MP2 methods. The calculated O-17 and C-13 NMR chemical shifts were compared with th e solution phase experimental data for the monocations. The structures and energies of a number of oxonium and carboxonium dications and the effect of diprotonation on the O-17 and C-13 NMR chemical shifts were also studied.
