Mass spectrometers are used by almost all chemists and many
researchers from neighboring disciplines such as physics, medicine,
or biology as a powerful a- lytical tool. Its advantages are high
sensitivity, speed, and almost no sample c- sumption. During the
last two decades, mass spectrometry experienced a boom of new
developments pushing its limits further and further at an
increasing speed just similar to the progress in NMR spectroscopy
in the 1970s. However, a mass spectrometer does not only serve as a
machine for solving complicated analytical problems, it evolved
meanwhile to a complete laboratory for the investigation of
molecules, clusters, and other species under the envir- ment-free
conditions of the highly diluted gas phase. These special
conditions existing only in high vacuum change the properties of
the particles under study significantly with respect to their
energetics and reaction pathways. For ex- ple, temperature is a
macroscopic property of a large ensemble of particles in thermal
equilibrium and is thus not defined for a single ion. This fact has
severe implications for the measurement of kinetic and
thermodynamic data of g- phase species. On the other hand, the
examination of gas-phase properties has the advantage that systems
reduced to minimum complexity can be studied more easily without
the complicated influences of solvents or counterions. In parti-
lar, the combination of isotopic labeling and mass spectrometry
allows for a detailed analysis of reaction mechanisms or
conformational analysis through H/D exchange experiments not only
on biomole
