摘要: Abstract The ion/molecule reactions of H 3 O + , NO and 2 with six monoterpenes (α-pinene, β-pinene, limonene, Δ -carene, myrcene, camphene) have been studied at 298 K 1.47 mbar using a selected ion flow tube (SIFT). rate constants the ionic products determined. It turns out that all occur collisional rate. Quantum chemical calculations were performed polarizability dipole moments studied, to determine constant Su–Chesnavich approach. Our results show monoterpene M proceed via proton transfer result in protonated molecules MH ( m / z =137) partly an =81. charge resulting mainly ionized C 10 16 . dissociative giving rise several products, which also observed electron impact spectra these monoterpenes.
