2,3‐dimethylnaphthalene (2,3‐DMN) crystallizes similar to naphthalene but with dipolar structural disorder of the acentric molecules. Quasielastic neutron scattering of the methyl groups between 12 and 270 K is studied for scattering vectors up to 17.7 nm −1 . The experimental results are fitted to a rotational jump model. From a fixed window experiment a broad band of activation energies around 1350 K is deduced.
