Steric effects in 5-membered rings—VIII : A conformational analytical study of cis- and trans-1,3-dichlorocyclopentane

A study of the title systems was performed using theoretical calculations, dipole moments (experimental and calculated) and NMR spectroscopy. The results were discussed in the light of literature data on related systems. It was concluded that a multitude of conformations occur in a potential well for the cis-isomer and that for the trans-one, an even flatter and more variegated distribution in a double minimum is indicated.
