Popis:	The 60 Mc/s proton spectra of methyl 2-bromo-3-fluoropropanoate and the 3-bromo-2-fluoro isomer have been analyzed completely with the aid of heteronuclear spin decoupling to illustrate an extension of the double resonance technique to ABCX spin systems. These results provide confirmatory evidence of the magnitude and relative signs of geminal and vicinal proton–proton and proton–fluorine coupling constants.
