“…In the case of CH 3 OH, the first two resonances produce only H − and CH 3 O − whereas the third one also leads to the formation of O − . It has also been observed that at the third resonance the hydrogen atom scrambles [50,51], revealing a larger lifetime against dissociation for this state. This is consistent with a Rydberg-like nature of the excited state seen in the absorption spectrum.…”

“…The process is thus related to the C-O bond cleavage in many alcohols (leading to OH À formation), with a band at a similar energy. 22,25,26 An indication of the expected energies of Feshbach resonances can be obtained from ionization energies, measured by photoelectron (PE) spectroscopy. The prediction is based on the observation that the energy difference between the 2 (c i…”

“…The energy distribution between the kinetic energy of the departing H-atom and the internal degrees of freedom in the initial fast step is to some degree statistical, that is, the (M À 1) À ion is generated with a distribution of internal energies. (The energy distribution of the departing H À ions has been measured for methanol 42 and a significant release of kinetic energy has been observed.) At least some of the (M À 1) À ions are thus generated hot enough to further dissociate thermally, with preference being given to the most stable fragments, closed shell molecules and ions, which 'boil off' from the primary (M À 1) À ion.…”
