This work focuses on quantifying the interactions between surfactant directing agent and silica precursor particles prior to and during the zeolite nucleation using Pulse-Field Gradient NMR method. Our results show the strength of the organic-inorganic association in mixtures that ultimately lead to zeolite formation under a wide range of conditions.
