摘要

Despite the importance of isoprene hydroxy peroxy radicals (RO_2) in the conversion of NO to NO_2 and hence in tropospheric ozone formation, no direct experimental studies have been carried out to investigate the kinetics of the RO_2-NO reaction. We report the first direct laboratory study of the rate constant for the isoprene RO_2-NO reaction using a fast-flow reactor coupled to chemical ionization mass spectrometry (CIMS) detection. By directly monitoring the peroxy radical, a rate constant of (9 ± 3) * 10~(-12) cm~3 molecule~(-1) s~(-1) was determined in the pressure range of 1 to 2 Torr and at a temperature of 298 ± 2 K. The measured rate constant is compared to the results of a recent theoretical prediction and indirect measurements and implications for the atmosphere are discussed.
