As in all mass spectrometric systems, the postulated ion structures cannot be directly verified, but recent advances in ion kinetic energy spectroscopy (see Section VI) allow one to prove that two ions of the same mass from different sources have either identical or differing structures. Ionic structures tend to be drawn based on common sense and chemical intuition. [Pg.262]

Zero electron kinetic energy spectroscopy provides a new tool in the study of chemical systems. In particular, it is applicable to molecules that are not in a bottle (metastable species) which nevertheless are of fundamental... [Pg.620]

Gas-phase acid-base studies are usually performed by using one of the following techniques high-pressure mass spectrometry (HPMS), chemical ionization mass spectroscopy (CIMS) with mass-analysed ion kinetic energy spectroscopy/collision induced dissociation (MIKES/CID), flowing afterglow (FA) or ion cyclotron resonance (ICR) spectrometry. For a brief description of all methods, Reference 8 should be consulted. [Pg.697]

Mass-analyzed ion kinetic energy spectroscopy (MIKES). This scan is implemented with reverse-geometry (BE-type) instruments, in which the front-end magnetic sector allows exclusive mass selection of a precursor ion [37], Fragmentation occurs in a region between the two analyzers (second FFR). A scan of the electric sector [Eq. (4.12)] yields a product-ion spectrum. MIKES also allows direct measmement of kinetic-energy release values. [Pg.131]

An improved, three-step synthesis of iV-butyl-l-deoxynojiromycin from D-glucose has been described, involving an enzymic oxidation ofN-butylglucamine. A synthesis ofA/ -[ C]methyl-1-deoxynojirimycin and its manno epimer has been reported in a study of glycosidase inhibition. l,3,4-Trideoxy-3-fluoronojirimycin and its manno epimer have been characterized and stereochemically distinguished by mass-analyzed ion kinetic energy spectroscopy. ...

The potential energy curve for ground-state NeN has its quasi-bound maximum 6.1 eV above the dissociation limit. The translational energy release associated with the NeN -> Ne + N process was determined by ion kinetic energy spectroscopy to be 6.5 0.5 eV [8] and calculated to be 5.51 eV [7]. [Pg.11]

The dication KrN was formed by a charge-stripping process from KrN. The appearance potential for the unimolecular charge-separation process KrN " Kr + N was measured to be 40 1.5eV. The translational energy release, Te = 6.0 0.2 eV, connected with this dissociation process was determined by ion kinetic energy spectroscopy [8]. [Pg.12]
