In the first part of the dissertation various types of hydrogen bonds, such as the O-H···O, the N-H···O and the N-H···Pi bridge in isolated heterodimeres of indole, phenol and naphthol with water and benzene, are analyzed. With Mass Analyzed Threshold Ionization (MATI), a combined technique of time-of-flight mass spectrometry and resonant multi-photon ionization (REMPI) in a cooled supersonic molecular jet, we successfully recorded cationic spectra of these systems and hence, among other things, precisely determined intermolecular binding energies. The analysis of the naphthol results was supported by ab-initio calculations. The second part of the dissertation deals with intramolecular, dissociative elektron-transfer (DET) in tailor-made ferrocene derivatives in the gas phase. Here, the DET takes place from a ferrocene unit to a covalent bound, locally photoionized chromophor unit with higher ionization potential.
