Dissociative attachment in ammonia

  • 1. Univ. of Nebraska, Lincoln, NE

Description

We have examined the total negative ion production from dissociative attachment of electrons to NH3 and ND3, and have found a vibrational progression not observed previously in the 5.65 eV peak. The vibrational spacing and Franck-Condon envelope are similar to those of the lowest Rydberg state of the neutral, in which the v2 out of plane bending mode is excited. We therefore assign the negative ion state to (1a1)2(2a1)2(1e)4(3a1)1(3sa1)22A1(C /sub 3v/ ), and suggest that fragment ions are produced through the negative ion analog of the predissociation process in NH3 (3sa1)3
