The available data on gas-phase basicities and proton affinities of approximately 1700 molecular, radical and atomic neutral species are evaluated and compiled. Theoretical investigations attribute the greater stability of α-protonated pyrrole to topological charge stabilization, rather than merely to the greater number of resonance contributors. Compendium of Chemical Terminology, 2nd ed. Blackwell Scientific Publications, Oxford 1997. Resolution is the inverse of resolving power and expressed as ΔM at M. Throck Watson, Lippincott-Raven, 1997, Ionization Methods in Organic Mass Spectrometry By Alison E. Resolution mass spectrometry Let two peaks of equal height in a at masses m and m - Δm be separated by a valley which at its lowest point is just 10% of the height of either peak.

The chemistry of mono-solvated anions is also increasingly becoming a topic of research. The structural elucidation of small molecules using mass spectrometry plays an important role in modern life sciences and bioanalytical approaches. It also examines the computational chemistry and theoretical calculations that provide complementary thermochemical, structural, and mechanistic information. Nicholas Housby, Springer, 2001, Mass Spectrometry Basics Christopher G. This publication constitutes an update of a similar evaluation published in 1984. Though α-protonation predominates thermodynamically, the kinetically favored β-protonated species is also observed for the first time in 3-4 times lower abundance under the conditions employed here.
