Collisionally induced dissociation mass spectrometric studies of perfluorinated 1H-heptane,tert-butanol, 2-butyltetrahydrofuran and isopropyl bromobutyl ether
摘要:
AbstractHigh‐energy collision‐activated dissociation in connection with mass‐analyzed ion kinetic energy spectrometry (CAD/MIKES) was employed to probe the structures of some ions generated by methane chemical ionization (CI) and negative ion chemical ionization (NICI) of the title compounds. CAD/MIKES results show that the [M H]− ion of lH‐perfluorobeptane and the [O(CF2)4Br]− ion of perfluoroisopropylbromobutyl ether are stable. The methane CI of these fluorocarbons also showed that the expulsion of HF molecules appears to be a major driving force for further fragmentations.
