Applications in gaseous ion and neutral chemistry using a six-sector mass spectrometer

Decarboxylation of metastable methyl benzoate molecular ions

“…Typical conditions have been reported elsewhere [5]: 200 A trap current in the electron ionization mode and 1 mA emission current in the chemical ionization mode.…”

Nitrosation of thiols and thioethers in the gas phase: A combined theoretical and experimental study

“…The mass spectrometric experiments were performed on a large scale tandem mass spectrometer (Micromass AutoSpec 6F, Manchester, UK) having a c 1 E 1 B 1 c 2 E 2 c 3 c 4 E 3 B 2 c 5 E 4 geometry, where E stands for electric sector, B for magnetic sector, and c for the collision cells [7]. Typical conditions were 8 kV accelerating voltage, 1 mA emission current (in the chemical ionization mode), 200 A (in the electron ionization mode), and 70 eV ionizing electron kinetic energy.…”

Interstellar molecules. Conversion of C 3 O − to C 3 O in the gas phase

“…The À NR spectrum recorded here is similar to the NR spectrum of C 3 O Á reported earlier. 11 Thus, neutral C 3 O can be made both by electron capture of C 3 O Á and charge stripping of C 3 O ÀÁ . Á…”

“…The linear species C 2 O 6 and C 3 O 7 [together with the associated propynal (HCC-CHO)] have been detected towards the dark molecular cloud TMC-1, while preliminary measurements suggest that C 5 O may also be present, but this is yet to be confirmed. 8 Neutral C 3 O has been made previously by a number of routes [9][10][11] including neutralisation of C 3 O Á . 11 Linear C 5 O has been synthesised from an anionic precursor.…”
