Resonant Soft X-ray Scattering (RSoXS) is an emerging, powerful technique to probe the nano-to-mesoscale ordering of polymers and other molecules. It joins together small-angle X-ray scattering (a statistical nanoprobe) with X-ray spectroscopy that brings with it unique chemical and bond-orientation sensitivity. Through over a decade of discovery and development, RSoXS is moving from a niche technique applied to organic electronic thin films to a plethora of new polymeric systems, measurement modalities, analyses, and simulation methods. This development promises to bring increasingly definitive answers to challenging questions in polymer science as well as expand its usefulness to complementary fields. A full synopsis of the technique, including background on the theoretical underpinnings, the practicalities of measurements including some best practices, and a review of RSoXS applications and discoveries is timely as it begins to impact a broader range of soft matter and polymeric fields.
