The use in Fourier-transform ion cyclotron resonance (FTICR) mass spectrometry of the collision-induced dissociation of proton-bound dimers, the kinetic method or Cooks's method, is tested. This method is compared with the proton-transfer equilibrium method. Good agreement between the two methods is observed. Advantages and limitations of the FTICR kinetic method are briefly discussed.
