Rotational excitations of methyl groups in six solid acetates have been investigated by 1 H nuclear magnetic resonance Ε½ . NMR relaxation time measurements at 15 MHz and 30 MHz and at temperatures between 10 K and the melting point. Hindering barriers between 1.6 kJrmol and 3.7 kJrmol have been foun
