Multiple quantum NMR was used to study a system of two adjacent methyl groups in an oriented molecule to see if there was any degree of correlated motion. The 4‐quantum spectrum which is sensitive to two‐body correlations can distinguish simply between the cases of uncorrelated and correlated motion. The experimental multiple quantum spectra of partially oriented 2,3‐dimethylmaleic anhydride in a liquid crystal show that the two methyl groups rotate quite independently.
