Laser photodissociation, velocity mapping

Arthur Suits is a professor of chemistry at Wayne State University where he and his group study the many roles office radicals—atoms or molecules with unpaired electrons—in chemical processes. One of the techniques developed in his lab, DC Shce Velocity Map Imaging, uses a video camera to record images of ions formed by photo ionization after (for one example) a dissociation reaction occurs. For instance, Suits has used laser photodissociation (Section 7.4) to break deuterium bromide ( HBr or DBr) into deuterium and bromine radicals. The photodissociation occurs at a fixed photon energy...
