Abstract
The CN+NO2 reaction was studied using time‐resolved infrared diode laser absorption spectroscopy. The total rate constant for this reaction over the temperature range 298–650 K was fit to the expression k1=10−10.30±0.03 exp[(171±32)/T], in reasonable agreement with previous measurements. Branching ratios at room temperature were also measured. The dominant product channel is NCO+NO, which accounts for 86.8±6.0% of the total reaction rate. The CO2+N2 and CO+N2O channels account for 5.6±6.0 and 7.6±3.2%, respectively. The dominant mechanism for this reaction is formation of an NCONO intermediate followed by O–N bond cleavage.Keywords
