NH2- formation by the attachment of electrons to NH3, NH2OH, NH2NH2 and NH2CH3 is studied using a low energy (0-10 eV), narrow electron beam. Formation of NH2- shows a narrow resonance with an onset around 4.5 eV and maximum around 6.0 eV from all these compounds. This slow variation of the appearance potential of NH2- within the series is rather unexpected from the energy balance equation since the bond energies vary considerably from one compound to the other.
