coefficients and productdistributions are reported for the reactions of fourth-row atomic cations from K+ to Se+, of fifth-row atomic cations from Rb+ to Te+ (excluding Tc+), and of sixth-row atomic cations from Cs+ to Bi+. Primary reaction channels were observed leading to O-atom transfer, OD transfer, and D2O addition. O-Atom transfer occurs almost exclusively (>or=90%) in the reactions with most early

selected reactions as a tool to further understand the reaction mechanisms, thermochemistry, and reaction kinetics. Reactions with CO are slow and typically yield complexes of the form M(CO)n+ (n = 1-2), with the second CO molecule appearing to be added faster than the first one. Reactions with CO2 also yield the formation of clusters; however, in the case of Ti+, the reaction produces the oxide TiO+
