The application of the atomic pair distribution function for the purpose of obtaining the intergrowth amount of pyrolusite (β-MnO2) and ramsdellite (R-MnO2) in γ-MnO2 is demonstrated. The presented model opens the door to intergrowth quantification in numerous materials where the two structural components are clearly distinguishable.
