Rapid Communications in Mass Spectrometry. Look first at the very strong peak at m/z = 43. Mass Spectral Interaction between the Functional Groups of Multiply Substituted Alkanes. 1. The plasma chromatograph as a qualitative detector for gas chromatography. An alcohol's molecular ion is small or non-existent. Ortho effects–I: Fragmentation mechanisms in some ortho‐substituted nitroarenes. International Journal of Mass Spectrometry and Ion Processes. Mitteilung über das massenspektrometrische Verhalten von Stickstoffverbindungen. Acetic acid as a liquid, with mobile phase of water and formic acid yes, it is acetic acid in the meantime we did a blank (thanks for the suggestion!) Chemical ionization over a wide range of pressures. Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. Some newer aspects of mass spectrometric ortho effects. Let's look at the mass spectrum of 2-methylbutane. Identification of a novel series of alkylitaconic acids in wood cultures of Ceriporiopsis subvermispora by gas chromatography/mass spectrometry. Identification of the isomeric phthalic acids by mobility and mass spectra. The mass spectra of maleic acid, maleic acid‐2,3‐d, fumaric acid and fumaric acid‐2,3‐d have been examined and fragmentation mechanisms are proposed for these compounds. IV: Carboxyl‐carboxyl interaction in some cycloalkane 1,2 dicarboxylic acids and its relationship with molecular geometry. 2-methylbutane is an isomer of pentane - isomers are molecules with the same molecular formula, but a different spatial arrangement of the atoms.
