Abstract
A distinction is drawn between methyl group rotation which occurs with the creation of a local strain in the host lattice due to coupling with low frequency lattice modes, and double proton pair exchange which leaves the lattice unchanged while cyclically permuting the proton space coordinates. The latter is subject to restrictions dependent on the proton spin states due to the exclusion principle but the former is not.
