Weak inter- and intra-molecular C delta+ F delta- center dot center dot center dot C delta+=O delta- interactions were theoretically evaluated in 4 different sets of compounds at different theoretical levels. Intermolecular CH3F center dot center dot center dot C=O interactions were stabilizing by about 1 kcal mol(-1) for various carbonyl containing functional groups. Intramolecular CF center dot center dot center dot C=O interactions were also detected in aliphatic and fluorinated cyclohexane carbonyl derivatives. However, the stabilization provided by intramolecular CF center dot center dot center dot C=O interactions was not enough to govern the conformational preferences of compounds 2-4.
