The solvent and temperature dependence of the 1H and 13C NMR spectra of 3-fluorobutan- 2-one (FB) and 3, 3-difluorobutan-2-one (DFB) are reported and the 4JHF, 1JCF and 2JCF couplings analysed using ab initio calculations and solvation theory. The solvent dependence of the IR spectra (carbonyl band) was also measured
