Abstract
The recent suggestion, based on gas-phase experimental data, that the most stable isomer of protonated benzene has a face-protonated pi-comp lex structure is not supported by our detailed computations which indi cate that the pi-complex is a second-order saddle point on the potenti al energy surface, lying 199 kJ mol(-1) higher in energy than the well -established C-2v sigma-protonated structure.
