Temperature dependence of the proton nuclear magnetic resonance spectra of some diamagnetic N,N-dialkyldithiocarbamate complexes of transition metals
MetadataShow full item record
Unusual structure and temperature dependent behavior of the proton nmr spectrum in a number of diamagnetic N,Ndialkyldithiocarbamate complexes of di- and trivalent transition metal ions, [M(CSLNRZ)~n ]=, 2, 3 may be accounted for by a total line-shape analysis in terms of an appropriate and general two-proton exchange model using a density matrix formalism. This has been done in detail for a limited range of basic, well-defined, simple, and representative members of the above series, using the diethyl-, di-n-propyl-, diisopropyl-, diisobutyl-, and dibenzyldithiocarbamates of nickel(I1) and cobalt(II1) Where possible a tentative physical interpretation of the model is given.
