Ion imaging is a multiplex detection technique that employs multi‐photon ionization and two‐dimensional time‐of‐flight mass spectrometry to obtain detailed information on the dynamics that govern the making and breaking of chemical bonds. It has primarily been used to study gas‐phase unimolecular photofragmentations, but can also be used to study bimolecular reactions and photoelectron processes. In many cases ion imaging permits the simultaneous measurement of reaction product branching ratios, quantum‐state populations and velocity distributions. © 1998 John Wiley & Sons, Ltd.
