---|---|---|---|---|---|
LimaKet | 7H6O | IPOH | 2A5O | 3A6O | |
Limonene + O3 | 0.0076 ± 0.0008 | 0.021 ± 0.001 | 0.160 ± 0.005 | 0.019 ± 0.003 | 0.015 ± 0.002 |
Limonene + O3 + CH | 0.0081 ± 0.0009 | 0.019 ± 0.003 | 0.050 ± 0.008 | 0.016 ± 0.003 | X |
Limonene + O3 (20 ppb NO) | 0.0052 ± 0.0005 | 0.008a | 0.11 ± 0.01 | 0.007a | 0.008a |
X –Indicates 3A6O was only observed in the Limonene + O3 (100 ppb) + CH experiment, no yield was measured.
Indicates yields based on data from 100 to 50 ppb O3 only just trace amounts of products were observed at 30 ppb O3.
