The performance of semiconductor devices based on conjugated polymers is strongly influenced by this microstructure yet it is difficult to fully characterize. This work investigates the potential of performing resonant diffraction at the selenium K\u2010edge to reveal new microstructural information about conjugated polymer thin films. By studying the variation of diffraction intensity as the X\u2010ray energy is varied across an absorption edge, resonant diffraction, also known as anomalous scattering, can provide new information about molecular packing within the unit cell. With its absorption edge at 12.66\u00a0keV, corresponding to a wavelength of \u223c 1 \u00c5, selenium K\u2010edge measurements allow for peaks corresponding to the smallest crystalline spacings (e.g.\n                    <jats:italic>\u03c0\u2010<\/jats:italic>\n                    \u2010\n                    <jats:italic>\u03c0<\/jats:italic>\n                    stacking) to be studied.
