PHOTOELECTRON-SPECTRA OF THE N-CHLORO AND N-BROMO DERIVATIVES OF DIMETHYLAMINE

The He I and He II spectra obtained for chlorodimethylamine (CH3)2NCl, and bromodimethylamine (CH3)2NBr, complete the study of the N-chloro and N-bromo derivatives of the small amines. The valence photoelectron spectra are interpreted with the aid of spindo molecular orbital calculations. Trends in the observed ionization energies for both series of small halo amines are described in terms of variations in inductive and resonance effects, the latter particularly concerning the nN/nxlone-pair interactions observed in the low ionization energy range. © 1979, CSIRO.
