The molecular ion of o ‐methoxy‐ d 3 ‐benzoic acid can undergo three different rearrangements and hydrogen/deuterium exchange between the functional groups. This can result in 14 isomers of the molecular ion before it decomposes giving fragments at m / z 105, 106, 107 and 108. Three types of isomer have been identified.
