DRAFT DEFINITION
Sustained off-resonance irradiation

A technique associated with Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry to carry out ion/neutral species processes, e.g. 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. As this consequence the ion's orbit does not exceed the dimensions of ICR (Penning) ion trap while the ion undergoing an ion/neutral species process keeps high (average) translational energy for an extended time frame.

Considered between 2004 and 2006 but not included in the 2006 PAC submission
