✦ Synopsis

Excitation functions of the NH( A 311-X '2; -, c 'II-a 'A) radiation following single-electron impact on ammonia were measured from 9 eV up to 160 eV. Several wavelength intervals of the NH emission spectrum were studied. For the A 'II-X 'Ztransition the excitation functions were found to vary with fragment rotation which reveals different dissociation mechanisms for slowly and rapidly rotating fragments. There is a strong indication that at higher impact energies a dissociation channel with simultaneous production of H (2s. 2p) atoms opens up.
