Mass spectrometry (MS) has become the central technique that is extensively used for the
analysis of molecular structures of unknown compounds in the gas phase. It manipulates the …

Mass spectrometry frequently reveals the existence of transient gas phase ions that have not
been synthesized in solution or in bulk. These elusive ions are, therefore, often considered …

Gaseous fragment ions generated in mass spectrometers may be employed as “building
blocks” for the synthesis of novel molecules on surfaces using ion soft-landing. A …

Isomeric quinolyloxenium cations were generated in the gas phase in an ion trap mass
spectrometer to explore their reactions. The structures of some products were identified via …

Coupling of the radical sites in isomeric benzynes is known to hinder their radical reactivity.
In order to determine how far apart the radical sites must be for them not to interact, the gas …

The gaseous 2, 6-didehydropyridinium cation and its derivatives transfer a proton to
reagents for which the reaction for their singlet ground states is too endothermic to be …

In der Massenspektrometrie werden häufig kurzlebige Ionen in der Gasphase beobachtet,
die zuvor nicht in Lösung oder in der Bulkphase synthetisiert worden sind. Diese schwer …

The gas-phase reactivities of several protonated quinoline-based σ-type (carbon-centered)
mono-, bi-, and triradicals toward dimethyl disulfide (DMDS) were studied by using a linear …

Examination of the reactions of σ‐type quinolinium‐based triradicals with cyclohexane in the
gas phase demonstrated that the radical site that is the least strongly coupled to the other …

The work described herein is related to gas-phase ion-molecule reactions studied by using
mass spectrometry. Chapter 2 describes density functional theory, a method used in …
