The 17 O chemical shifts of seventeen variously substituted oxiranes have been measured in CDCI 3 solution. Deviations of δ o from additivity have been interpreted in terms of steric effects and loss of conjugation. Moreover, in the case of certain cis ‐ and trans ‐dimethyl‐substituted compounds, 17 O NMR allows a differentiation between the different molecular configurations.
