By a series of nuclear magnetic double-resonance experiments it is shown t-hat the geminaL H-H and H-C ccupling constants of group IV hydrides are increasing from C to Pb in accordance with a -qualitative argument on the basis of molecular orbital theory.
GUTOWSKY, Karplus and Grant' have found that the spin-spin coupling constant between methylene protons depended on the H-C-H bond angle of the methylene group and also suggested that some other factors 1
The proton-coupled 13C NMR spectra of 2-, 3-and 4-fluoropyridines were completely analysed and the signs and magnitudes of the 13C-1H coupling constants determined. The root mean square deviations of the observed J(CH) values from those calculated using empirical correlations between the coupling co
