Spectroscopic states and dissociation of negative molecular ions of dimethoxyamine

Chemical reactions are often discussed in terms of the Woodward-Hoffmann symmetry rules at the basis of which is the conservation law for total angular momentum in a conservative system. If, during a reaction, there is no spin-orbital interaction and the nuclear orbital and spin moment are not coupled with the angular momenta of the electrons, the orbital angular momentum of the electrons is conserved. Using these hypotheses along with expressions for the electronic wave functions the authors of this paper study the dissociative electron capture by dimethoxyamine molecules and molecular ions for the purpose of developing an understanding of the orbital correlation of the fragment ions with the negative molecular ions. The photoelectron spectra and the form of the molecular orbitals of the compound, the molecular ions, and the fragment ions were determined and interpreted using quantum-mechanical CNDO/2 and PNDO methods.
