  "abstract": "Phenomena responsible for emerging technologies originate from novel molecular states at buried interfaces. Yet quantitatively resolving these features is out of reach in most cases. Resonant soft X-ray scattering (RSoXS) has demonstrated sensitivity to these local states but is limited due to a lack of accurate interpretive models and spatial resolution. Here we demonstrate a machine learning (ML)-optimized optical model that establishes the direct and quantitative interpretation of molecular orientation, chemical identity and packing states with sub-monolayer resolution - reaching beyond the diffraction limit. We discover a gradient evolution of molecular orientation and packing emerging from a pinned state directly at the channel-dielectric interface of an organic transistor, indicative of competing surface versus bulk growth dynamics that contradict models based on substrate patterning. This non-destructive insight into buried interfacial formation and final configuration opens possibilities in controlling interfacial states and phenomena in next-generation technologies.",
