DRAFT DEFINITION
Sustained off-resonance irradiation

A technique associated with Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry to carry out ion/neutral reactions such as low-energy collision-induced dissociation. A radio-frequency electric field of slightly off-resonance to the cyclotron resonance frequency of the reactant ion cyclically accelerates and decelerates the reactant ion that is confined in the ICR Penning ion trap. The ion's orbit does not exceed the dimensions of ion trap while the ion undergoes an ion/neutral species process that produces a high average translational energy for an extended time.
