Observation of wavelength‐sensitive mass‐independent sulfur isotope effects during SO 2 photolysis: Implications for the early atmosphere

Mass‐independent isotopic signatures for δ 33 S, δ 34 S, and δ 36 S produced in the photolysis of sulfur dioxide exhibit a strong wavelength dependence. Photolysis experiments with three light sources (ArF excimer laser (193 nm), mercury resonance lamp (184.9 and 253.7 nm), and KrF excimer laser …
