Sustained off-resonance irradiation

Term · Chemistry · MLC-T-CHM-011706

A technique used in mass spectrometry, particularly in ion traps, to excite ions for collision-induced dissociation. It involves applying a radiofrequency field slightly off the resonant frequency of the ions, causing them to gain kinetic energy through multiple low-energy collisions with a buffer gas. This method provides a controlled way to fragment ions for structural elucidation.
