  AbstractThe 1H and 13C NMR spectra of 3,3,‐diiodotetramethylpentane (2), 3,3‐dibromotetramethylpentane (3), and 3,3‐dichlorotetramethylpentane (4) are temperature dependent. The activation parameters for the tert‐butyl group rotation in 2–4 have been determined. The 13C NMR chemical shifts are discussed.
