The NMR spectrum of methylenecyclopropane oriented in two nematic phases has been measured at 240 and 400 MHz. Ratios of the proton‐proton distances have been obtained. These values are compared with those deduced from the structure of the molecule in the gaseous state; they suggest an increase of the ethylenicangle in the nematic phase.
