Structure-sensitive dissociation scheme for three isomers of difluorobenzene

Three isomers of difluorobenzene were multiply ionized by low-energy collisions with Ar8+, and their subsequent dissociation was studied using position-sensitive time-of-flight (TOF) measurements combined with a coincidence technique. The vector correlation of the velocities of the two F+ fragment ions was examined and found to be sensitive to the structure.
