Ammonia activation by Sc sup + and Ti sup + : Electronic and translational energy dependence
- Univ. of Utah, Salt Lake City (USA)
The reactions of Sc{sup +} and Ti{sup +} with ammonia are studied as a function of translational energy in a guided ion beam tandem mass spectrometer. The effect of electronic energy for the Ti{sup +} reactions is also probed by varying the conditions for forming Ti{sup +}. Excited doublet states of Ti{sup +} are found to be much more reactive than the a{sup 4}F ground and b{sup 4}F first excited states. Both metals form the MH{sup +}, MNH{sup +}, and MNH{sub 2}{sup +} products, while only Ti{sup +} forms MN{sup +}. The results are consistent with reaction that occurs primarily through a covalently bound insertion intermediate, H-M{sup +}-NH{sub 2}, having a singlet and doublet spin state for M = Sc and Ti, respectively.
