## Abstract Urea:__n__‐paraffin inclusion compounds have been formed through sonification of urea with pure paraffin liquids. Raman microprobe spectra of individual microcrystals (5–50 μm in size) of these materials are interpreted in terms of a non‐planar conformation for the included paraffins. A
Urea adducts with n-octane, n-decane, n-dodecane, n-tetradecane and nhexadecane have been studied as stationary phases in gas chromatography. With all the adducts examined, selective sorption of n-alkanes and of branched alkanes with a single methyl group in the side-chain was found. This sorption i
