Abstract
We have measured the temperature T and Larmor frequency ω/2π dependence of the proton spin‐lattice relaxation rate R in solid 1‐hydroxy‐2,4,6‐tri‐butylbenzene. The data is interpreted in terms of the rotational motion of the t‐butyl groups and their constituent methyl groups. Our data is much more extensive than a previous report [J. Yamauchi and C. A. McDowell, J. Chem. Phys. 75, 1051 (1981)] resulting in a revised dynamical model and considerably larger rotational barriers. Interesting thermal history effects are discussed.
