Dissociative Electron Attachment to Polyatomic Molecules - V : Formic Acid and Propyl Amine

In this paper, we discuss the dissociative electron attachment process in Formic Acid and Propyl Amine. These are molecules containing more than one functional group and have low symmetry (Cs group). We measured the kinetic energy and angular distributions of fragment H^{-} ions from the resonances observed in these molecules and compared with that in the precursor molecules, namely - Water, Ammonia and Methane. Measurements suggest that the dissociation dynamics in bigger molecules are independent of overall symmetry of the molecule, rather depend only on the local symmetry of functional group and bond orientation factors.
