The C-1 3 nuclear Ove&wer e~~rne~t 0 in Proto decoupled NMR spectra is redu& by pammagnetic metal ions. The similarity of the Iimiting intensities for various ions suggests the NOE is quantitatively eliminated, with the "three &n effect" relatively urimportaJ&
## Abstract High resolution proton decoupled ^13^C and ^31^P n.m.r. spectra of bis(diphenylphosphino)acetylene in (CD~3~)~2~SO and CDCl~3~ are analysed as ABX spectra to give the relative chemical shifts of the ^13^C and ^31^P nuclei as well as the spinβspin coupling constants ^3^__J__(PP) and ^__n
## Abstract The feasibility of the application of selective ^13^Cο£Ώ{^1^H} nuclear Overhauser effect (NOE) measurements to organic structural analysis in ^13^C NMR spectroscopy has been investigated at 25 MHz using citraconic anhydride and the methyl ester of pentalenolactone as model compounds.
