— In 1, 1, 2‐trichlorotrifluoroethane solution biliverdin physically quenches singlet oxygen at a rate of 8 × l0 s M‐ 1 s ‐1 and reacts chemically at 6 × 10 5 M‐ 1 s ‐1 to give a red product. In D, O solution the rate constants are PD dependent and range from 1.5–6 times 10 10 M‐ 1 s ‐1 for quenching and the chemical rate varies from 3–5 × 10 8 M ‐1 s ‐1 to give colorless products.
