Implication

Comprehensive spectroscopic analysis of nitric oxide transitions improves accuracy in high-temperature environments, indicating significant advancements for diagnostics and monitoring.

Key Points

This work aims to investigate nitric oxide absorption transitions at high temperatures and quantify associated uncertainties.
Used laser absorption spectroscopy across two experimental systems: a continuous flow gas cell and a shock tube facility.
Measured line intensities and temperature dependence coefficients in four buffer gases (Ar, N₂, He, CO₂) at temperatures up to 1742 K.
Developed methodologies for uncertainty mapping and dynamic evaluation.
Achieved exceptional line intensity measurement accuracy with uncertainties as low as 0.75%.
Notable 13-fold and 3.5-fold reductions in uncertainty for scanned-wavelength and fixed-wavelength laser absorption spectroscopy, respectively.
Revealed distinct gas-specific interactions, especially the weak interaction of NO with helium.
