The present article is the second part of a general overview of the gas-phase protonation thermochemistry of polyfunctional molecules. The first part of the review (Mass Spectrom. Rev., 2007, 26:775-835) was devoted to the description of the physico-chemical concepts and of the methods of determination, both experimental and theoretical, of gas-phase basicity. Several clues concerning the structural and energetic aspects of the protonation of isolated species have been emphasized. In the present article, specific examples are examined. The field of investigation is limited to molecules containing a "saturated" basic site, that is, nitrogen or oxygen atoms engaged in simple σ bonds with their neighboring. Aliphatic, cyclic and aromatic poly-amines, amino alcohols, alcohols, ethers, and hydroxyl-ethers, are successively presented.

Professor Wolfgang Luttke zum 60. Geburtstag gewidmet Die Konformation organischer Molekiile laRt sich durch Photoelektronen-(PE-)Spektroskopie bestimmen, wenn vom Diederwinkel abhangige Orbitalwechselwirkungen vorliegen. Die Anwendung des Verfahrens setzt voraus, daB sich die entscheidenden Ionisationsbanden eindeutig zuordnen lassen und induktive Effekte sowie sekundare Orbitalwechselwirkungen ausgeschlossen oder beriicksichtigt werden konnen. In vielen Fallen ist das Verfahren komplementar zu den konventionellen Methoden. Die PE-spektroskopische Konformationsanalyse eignet sich insbesondere fur Verbindungen mit benachbarten freien Elektronenpaaren oder rr-Systemen.

The conformation of organic molecules may be determined by means of photoelectron (PE) spectroscopy if there are orbital interactions present which depend on a dihedral angle. Straightforward application of the method requires that all ionization bands of interest can be assigned unambiguously and that inductive effects and secondary orbital interactions do not occur or can be accounted for appropriately. In many cases, this method complements conventional methods of conformational analysis. PE conformational analysis is particularly suited to compounds containing vicinal lone pairs or π systems.
