C1srelated

C1s-related is a term used in spectroscopy and materials science to denote content, data, or analyses that concern the carbon 1s core level and its related spectral features. It is commonly encountered in datasets, software tagging, and research notes where information related to carbon core-level spectroscopy is grouped for easy retrieval, particularly in studies using X-ray photoelectron spectroscopy (XPS) or near-edge X-ray absorption fine structure (NEXAFS).

In XPS, the C 1s peak is a central feature, typically appearing near 284.8 eV for adventitious carbon. Shifts in this peak can indicate changes in chemical state, such as C–C or C–H bonds versus C–O, C=O, or O-C=O groups. C1s-related data often include binding energy values, peak fitting parameters, and chemical-state deconvolution, sometimes with reference standards to ensure consistency across measurements and laboratories.

Applications of C1s-related data span material characterization across polymers, carbon-based materials, organic electronics, coatings, and composites. It also plays a role in data management and reproducibility, where researchers tag datasets or software outputs with C1s-related metadata to indicate relevance to carbon 1s spectroscopy and analysis.

Challenges include instrumental calibration, charging effects, hydrocarbon contamination, and variations in peak fitting methods. Because C1s-related is not always a standardized label, researchers may need to specify the exact context, such as the spectroscopy technique, reference standard, or chemical states involved.
