The gas-phase reactions, C(¹D) + NO and C(¹D) + O₂ have been studied over the 50-296 K range using a Laval nozzle reactor. C(¹D) atoms were produced by CBr₄ photolysis. A tracer technique was employed to follow the kinetics by adding H₂ or CH₄ to the flow. H-atoms produced by the C(¹D) + H₂/CH₄ reactions were detected by laser-induced fluorescence. Rate constants for the C(¹D) + O₂ reaction show little variation with temperature, whereas rate constants for the C(¹D) + NO reaction increase rapidly below 100 K. Numerical simulations were performed to evaluate the influence of secondary reactions.

C（的反应¹ d）与氧分子轴承NO和O ₂在低温

使用拉瓦尔喷嘴反应器在50-296 K范围内研究了气相反应C（¹ D）+ NO和C（¹ D）+ O ₂。通过CBr ₄光解产生C（¹ D）原子。通过向流中添加H ₂或CH ₄，采用示踪技术跟踪动力学。由C（¹ D）+ H ₂ / CH ₄反应产生的H原子通过激光诱导的荧光进行检测。C（¹ D）+ O ₂反应的速率常数随温度变化不大，而C（¹D）+ NO反应在100 K以下迅速增加。进行了数值模拟，以评估副反应的影响。
