Proton nmr. 3 and fluorine nmr. 4 spectroscopy have been utilized for structure determinations of substituted cyclopropanes. Coupling constants and chemical shifts of cyclopropane derivative^^.^ have recently been reported and interpreted in terms of substituent effects and molecular geometries. R In the present research, the spin-spin splittings in the proton nmr spectra of several substituted cyclopropanes have been ...
