We developed a method for analyzing time-of-flight spectra of Secondary products from sequential dissociation reactions fol-lowing photon absorption by the parent molecule. This work complements the original discussion by Kroger and Riley, and shows that substantial information can be extracted even from highly aveyaged data. This information includes the average translational energy release and anisotropy of the secondary pro-duct recoil, as well as the relative yields of the secondary frag-ments for competing pathways. Model results are examined in order to illustrate the basic features of secondary dissociation.
