Popis:	EVIDENCE for cis–trans isomerism of the conjugated systems of molecules with bond-structures analogous to that of butadiene has frequently been sought (refs. 1 and 2 summarize earlier work), but it is often difficult to establish its occurrence. The possibility of such isomerism obviously exists in the case of acrylic acid, but electron diffraction3 and vibrational spectroscopy4 have given no clear evidence. We have found that the microwave spectrum of acrylic acid shows it to contain comparable proportions of isomers with the planar structures I and II in the gas phase
