Methylene bending mode analysis (1400-1500 cm-1 region) and dipole moment determinations are carried out in the dissolved state (solvent CCl4) for fluoropropanone (I) and 1,3-difluoropropanone (II).The results are consistent with the existence of two conformations, "cis" and "trans", for (I) and one conformation "cis-trans" for (II).Theoretical evaluations of conformer stabilities by the PCILO method and Onsager formalism are in reasonable agreement with these experimental results.
