摘要：

The temperature dependence of the C-13 CP/MAS NMR spectrum of solid tri-tert-butylmethanol and three similar trialkylmethanols is reported. That energy barriers are 20-30% higher than found in solution is attributed to constraints of the lattice which also seem to cause the rotation and libration processes for these molecules to merge into a single process. The complications that may be encountered when studying dynamic NMR behaviour in solids are also discussed.
