The formation of fragment negative ions from CH3I on low energy electron collision (0-50 eV) has been measured using a pulsed electron beam and pulsed ion extraction setup in a crossed-beam geometry. In addition to I we have observed Hand CH at specific resonant energies due to dissociative electron attachment to CH3I. The cross-sections were put on an absolute scale using the relative flow technique. We have also carried out ab initio molecular orbital calculations to derive information on the ground state potential energy surfaces of CH3I, CH3I and their various dissociation products.
