The photodissociation dynamics of XCN molecule has been the subject of interest in recent years because the cyano radical (CN) can be considered a pseudo halogen due to its high electron affinity. So XCN may be viewed as a pseudo-bi-halogen, where X represents a halogen atom such as chlorine or bromine. The interesting property of the molecule is that both fragments, CN and Cl/Br, have positive electron affinities (EACl = 3.621 eV, EABr = 3.365 eV, and EACN = 3.82 eV) and as a result dissociative electron attachment is possible [12], [13], [14] and [15]. Moreover, chlorine and fluorine containing molecules have special interest in atmospheric science because these molecules are involved in the depletion of ozone layer in the stratosphere. Possibilities of different dissociative pathways of FCN and ClCN have been shown earlier
