Novel ssNMR pulse sequences will be applied to probe the site-specific motional dynamics of the crystalline systems, polymers, and their hybrid materials, whose structures could be altered as a response to external stimuli. This fundamental study will unravel the molecular events governing the stimuli responsivity of the studied systems. The molecular insights will provide a road map to develop novel stimuli responsive systems for real applications.;solid-state NMR; 13C NMR; spin locking
