We report a rapid solid−state 35/37Cl NMR strategy for 3D organic−inorganic hybrid and low−dimensional (2D and 0D) all−inorganic lead−based perovskites embracing ultra-wideline acquisition approaches and moderate to ultrahigh magnetic fields. The observed quadrupolar NMR parameters (CQ and η), supported by GIPAW−DFT computations, revealed distinct features for unique local Cl environments with the variation of the A−site and dimensionality. 35Cl CQ values display the potential for becoming an informative probe of distinct Cl chemical environments.
