放电流-EPR技术已被用于测量OH与HNO 3反应的速率常数和产物分布，这对平流层建模很重要。在251-403 K范围内，速率常数为（7.3±2）×10−15 exp[876±85）/T] cm 3 molecule−1 s−1。此外，用NO原位滴定NO_3的结果表明，在室温下，OH与HNO_3反应只生成NO_3和H_2O。
The discharge flow‐EPR technique has been used to measure the rate constant and the product distribution for the reaction of OH with HNO3, which is important for stratospheric modeling. The rate constant is found to be (7.3±2)×10−15 exp[876±85)/T] cm3 molecule−1 s−1 in the range 251–403 K. Besides, the in situ titration of NO3 by NO has shown that the reaction of OH with HNO3 only produces NO3 and H2O at room temperature.
