A theoretical study of the nuclear magnetic resonance spectra given by ABCD systems in fused aromatic rings is presented. The symmetry of these systems allowed much simplification and equations developed for an R-AB-X case made possible the allocation of the lines to specific transitions. Examples are given to show how the theoretical treatment makes possible an analysis of observed spectra.

Reactions between niobium(V), tantalum(V), and protactinium(V) chlorides and bromides and sodium N,N-diethyldithiocarbamate (Nadtc) have been examined in non-aqueous, non-oxygenated organic solvents. Complexes obtained are of the types Mdtc4X, Mdtc3X2, Mdtc3S, Mdtc2X3, and Mdtc2X3.nC6H6 (n = 0.7–1.0); not all complexes have been isolated for each metal. Within each group the niobium(V) and tantalum(V) complexes are isostructural; possible structures are discussed in the light of results from infrared (i.r.) and nuclear magnetic resonance (n.m.r.) spectra, molecular weight, and electrical conductivity measurements.
