A wide range of sodalite framework materials, M-8[TT'O-4](6)X-2 where T = Al, Ga, Si, T' = Be, Al, Si, Ge, have been characterized using Al-27, Si-29, and Ga-71 magic angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy. Structural parameters, such as functions of the framework T-O-T' angle, correlate linearly with the determined chemical shift values and provide relationships, as a function of T', which will facilitate characterization of more complex zeolitic compounds containing such species. The effects of changing a particular neighboring framework cation on the resonance position is controlled by variations in both framework bond angles/distances and electrostatic effects, these contributions are resolved.
