Total Scattering – Pair Distribution Function - General Information
Total scattering
Total scattering (TS) goes beyond typical assessment of diffraction peaks to consider the diffuse intensities scattered underneath and in between. These carry further information about defects, disorder, dynamics, and morphology that underpin functional properties.
Pair distribution function
The pair distribution function (PDF) analysis gives an alternative perspective to the total scattering signal by transforming the data to a spatial dependence, allowing properties such as bond lengths, correlated motions, and local structural features to be observed directly.
