A canonical transformation technique generalized for the case of a non‐periodical time dependence of the Hamiltonian is used for the analysis of molecular motion influence on multipulse NMR high resolution spectra in solids. The linewidth is shown to be described in some cases by a temperature‐dependent effective Hamiltonian.
