Abstract: Aformula for estimating the chemical shifts of protons on saturated carbons of compoundsof small rings is presented:δH=A+ΣΔα+ΣΔβ. The average error of calculated shift is 0.19 ppm for protons on cyclopropane, 0.15 ppm for cyclobutane, 0.16 ppm for cyclopentane.The chemical shifts depend on the substituents and the class of the rings.The base value Ain the formula is a representation of ring strain.

Key words: Proton chemical shift, Cyclopropane, Cyclobutane, Cyclopentane, Ethylene oxide
