Název v původním jazyce

Selected Ion Flow Tube, SIFT, Studies of the Reactions of H3O+, NO+ and O2+ with Eleven C10H16 Monoterpenes.

Popis výsledku v původním jazyce

The reactions of H3O+, NO+ and O2+ have been studied with the 11 terpenes, myrcene, ocimene, alpha- and beta-pinene, alpha- and gamma-terpinene, 2- and 3-carene, R- and S-limonene and camphene, at thermal energies using a selected ion flow tube (SIFT). This study was intended to explore the potential of SIFT mass spectrometry (SIFTMS), for analysing terpenes in air. All 33 reactions are seen to proceed at the collisional rate and multiple product ions result. The H3O+ reactions result in two major ion products, the stable protonated terpenes C10H17+ together with C6H9+ ions, with some minor products (a few percent) in some reactions. The NO+ reactions result in the parent cations, C10H16+, as the major product ion together with several fragment ions, notable C7H9+. The appearance of the minority adducts H3O+M and NO+M provide clues to the mechanisms of these reactions. The more energetic O2+ ions result in greater fragmentation and the parent terpene cations are only minority products.
