## Abstract The base peak and highest mass number in the spectra of tropylium iodide and bromide corresponds to the mass of the cation. Both appearance potential (AP) measurements and the fragmentation pattern strongly indicate that the gaseous species present is the tropylium radical. Rediction to
Multi-photon excitation in a time-of-flight mass spectrometer (TOF-MS) is shown to lead to threshold ions with defined internal energy. A powerful technique for the production of threshold ions is based on the excitation of high long-lived Rydberg states embedded in the ionization continuum. The Ryd
