title: Radiative stabilization of trimethylsilyl adduct ions.
abstract: Ketones and phenol react with trimethylsilyl ions to form adduct ions by radiatively or collisionally stabilized addition reactions, in contrast to aliphatic alcohols and ethers, which react with trimethylsilyl ions to form adduct ions by a rapid two-step process. Secondorder rate constants for the addition of trimethylsilyl ions to acetone were independent of pressure from 3×10(-7) to 50×10(-7) tort at room temperature; consequently, the adduct ions, [M+73](+), are formed primarily by radiatively stabilized addition in these ion cyclotron resonance experiments.
