NMR spectra of tetravinylsilicon, methyl-, and ethylvinylketone have been analyzed. The parameters found do not agree with those previously reported for the same compounds by other authors, although the source of several experimental data is the same; the coupling constants agree well with values already known for other vinyl compounds and correlate satisfactorily with the electronegativities of the elements bonded to the vinyl group.
