The n.m.r. spectra of some 1,2,2‐trisubstituted cyclopropanes are reported. Coupling constants and chemical shifts of the cyclopropane protons and their dependence on substituent effects are discussed. Conformations of benzylcyclopropane derivatives are investigated by long range magnetic shielding. The concentration dependence of the n.m.r. spectra of some 1,3‐diols is explained by inter‐ and intramolecular hydrogen bonding.
