通过闪光光解共振荧光技术测量了羟基自由基与硝酸在225-443 K温度范围内的反应速率常数。高于 300 K 时，速率常数趋于平稳，这种方式只能用两个反应通道的出现来解释，其中一个在低温下运行，通过形成加合物中间体进行。讨论了这些速率常数值对平流层反应常数的影响。
The rate constant for the reaction of hydroxyl radicals with nitric acid in the 225-443 K temperature range has been measured by means of the flash photolysis resonance fluorescence technique. Above 300 K, the rate constant levels off in a way that can only be explained by the occurrence of two reaction channels, of which one, operative at low temperatures, proceeds through the formation of an adduct intermediate. The implications of these rate constant values for stratospheric reaction constants is discussed.
