Simulated Raman libraries of gaseous CO, H2, N2, O2, CO2, and H2O for high-temperature diagnostics

In this paper, we present libraries of simulated Raman spectra of di- and triatomic gaseous species relevant for reactive flows in high-temperature environments such as flames, ranging from 1 to 2500 K. The libraries encompass the most abundant isotopologues for key species, including CO . Simulation methodologies and results were primarily drawn from and validated in previous studies, with additional validation data provided in this work. Compiled into directly usable line lists and pseudo line lists, the simulated spectra are available in an online repository to support research groups engaged in species concentration determination, temperature measurement, and other Raman spectroscopy applications. • Simulated Raman libraries for high-temperature diagnostics in reactive flows. • Temperature-dependent line lists from 1 to 2500 K in 1 K increments. • Coverage of key isotopologues and advanced intramolecular interactions. • Spectra provided in two polarization configurations: [XX] and [XY]. • Libraries are freely available in an online database.
