POSITIVE AND NEGATIVE ION MASS SPECTRA OF RING - SUBSTITUTED NITROBENZENES
نویسندگان: ثبت نشده
چکیده مقاله:
The 70 ev positive and negative ion mass spectra of ring-substituted nitrobenzenes were studied. The influence of the substituent group on the fragmentation modes of the molecular ions is discussed. The effect of pressure in the formation of negative ions was also studied. As expected, the ratio of fragment ions to negative molecular ions decreased with increasing pressure in ion source.

Positive and negative ion fast atom bombardment mass spectra of some penicilloic acids.
The technique of fast atom bombardment mass spectrometry has been shown to be capable of producing molecular weight and useful fragmentation information from a selection of penicilloic acids. In addition, the technique has been shown to give similar information on alkali metal salts of penicilloic acids.
متن کاملMass Spectra and Photodetachment of Sodium Fluoride Negative Ion Clusters
A flowing afterglow discharge ion source with NaF vaporized into the flow produces the expected stable anions F-(NaF),, as well as the unusual species Na(NaF); and (NaF); (n < 17). The dominance of (NaF); suggests that it has a particularly stable structure. A fixed-frequency laser has been used to photodetach electrons from mass-selected ion beams extracted from the flowing afterglow. Photoele...
متن کاملNegative ion mass spectra of some polychlorinated 2-phenoxyphenols.
Polychlorinated 2-phenoxyphenols were studied by negative ion mass spectrometry. Common to almost all of the methane enhanced negative ion mass spectra were (M-1)-, (M-36-)-., (M-37)-, (M-72)-., and chorinated quinoxide ions. The (M-36)-. ion does not apparently form in a mechanism analogous to the thermal or photochemical ring closure of these compounds to form the chlorinated dioxins. The chl...
متن کاملEffect of protein stabilization on charge state distribution in positive- and negative-ion electrospray ionization mass spectra.
Changes in protein conformation are thought to alter charge state distributions observed in electrospray ionization mass spectra (ESI-MS) of proteins. In most cases, this has been demonstrated by unfolding proteins through acidification of the solution. This methodology changes the properties of the solvent so that changes in the ESI-MS charge envelopes from conformational changes are difficult...
متن کاملComparison of negative ion electrospray mass spectra measured by seven tandem mass analyzers towards library formation.
A library of negative ion electrospray ionization mass spectra and tandem mass spectra (MS/MS) of sulfonated dyes has been developed for fast identification purposes. The uniform protocol has been elaborated and applied to the measurements of more than 50 anionic dyes. Three collision energies are selected in our protocol which ensures that at least one of them provides a suitable ratio of prod...
متن کاملEffects of anions on the positive ion electrospray ionization mass spectra of peptides and proteins.
Positive ion electrospray ionization mass spectra of polypeptides are usually obtained from solutions that are acidified and therefore contain relatively high concentrations of anions. The present study describes an investigation of the effects of these ubiquitous anions on the positive ion electrospray ionization mass spectra of peptides and proteins. Certain anionic species in the spray solut...
