THE COUPLING. : R+W Couplings
2019-11-1 · Geminal coupling between protons (with values between -23 and +42 Hz) depend mainly on the H–C–H bond angle, the influence of and substituents and the hybridization of the carbon. H H H H H H 2JHH = -12.5 Hz 2JHH = -4.3 Hz 2JHH = 2.5 Hz . These values can be affected by the nature of the -substituents: ...
