Millisecond decay rates of the perdeuterio benzene cation (C6D6+) are measured in two different ion storage equipments. Resonance-enhanced two photon ionization with a single laser beam leads to the production of the perdeuterio benzene cations witho

By using the technique of mass-analyzed threshold ionization spectroscopy, we were able to measure ionization energies of indole−Ar (62505 cm-1), indole−H2O (59433 cm-1), and the indole−benzene (59833 cm-1) complexes, as well as their dissociat

The nature of the intermolecular bonding in the indole−water complex is investigated by highly resolved UV-REMPI spectra with rotational fine structure. First, we determine the coordinates of the amino hydrogen atom by isotope substituting it with
