Production of highly oxidized organic compounds from ozonolysis of beta-caryophyllene : laboratory and field measurements
We conducted a laboratory investigation to identify highly-oxidized organic compounds formed in sesquiterpene (C15H24, SQT) ozonolysis. The dominant sesquiterpene previously identified from branch emissions of Scots pine, beta-caryophyllene, was used for this study. Using the latest mass spectrometr...
