MICROWAVE SPECTROSCOPY OF MONOTERPENES OF ATMOSPHERIC INTEREST: α-PINENE, β-PINENE, AND NOPINONE

摘要

Several monoterpenes and terpenoids are biogenic volatile organic compounds which are emitted in the atmosphere, and react with OH, O_3, NO_x, etc. to give rise to several oxydation and degradation products. Spectroscopic information on these atmospheric species are still very scarse. Meanwhile we have demonstrated that combining quantum calculations to microwave spectroscopy led to the unambiguous characterization of the most stable conformers for perillaldehyde, limonene and carvone. This information can be used to subsequently model accurately the vibrational signature for atmospheric purposes.
