possible in the twist conformation. The 1-(4-fluorophenyl)cyclopentyl cation also exists in the twist conformation. The ratio of ..beta..-CD/sub 2/ to ..beta..-CD/sub 3/ effects in these and other cations indicates that hyperconjugation is stronger for endocyclic methylene bonds than for exocyclic methyl bonds. A theoretical model, based on MINDO/3 calculations and a perturbational approach, provides a possible

The assignment of the splitting of the ν(CO) mode in cyclopentanone is reassessed through an extensive vibrational study, including temperature and solvent variation studies, isotopic substitution, and ab initio calculations of monomer and dimer structures and spectra. The results show that the assignment of the splitting of the ν(CO) mode to Fermi resonance is based on several of erroneous observations
