Using high-resolution solid-state 15 N cross-polarization magic angle spinning NMR techniques, the proton transfer thermodynamics and dynamics and the proton locations in polycrystalline 15 N-labeled porphycene were studied. Whereas at room temperature only a single 15 N resonance is observed, indic
