Abstract  

An Auger event triggered by electron-capture (EC) decay of 57 Co incorporated in a chelate molecule results in the loss of an average of 5 electrons. During subsequent charge neutralization, the molecule acquires >50 eV of excitation energy. Only molecules having a large -electron system were found to escape fragmentation. The fate of the molecule was followed by the 14.4 keV Mössbauer emission which occurs 10-7 second after the EC event. For a conjugated molecule to survive fragmentation, it should be able to disperse its energy in a time interval shorter than the period of atomic vibrations. We had proposed earlier that p-electrons undergo collective excitation and that the plasmon decays in <10-14 second accompanied by ejection of an electron leaving the molecule unscathed. Intermolecular energy transfer is not important and even an isolated molecule of 57 Co(II) phthalocyanine encapsulated in a zeolite supercage escapes fragmentation following an Auger event. Our model for rapid disposal of large excitation energy receives additional support from recent reports of single or mulitphoton plasmon excitation (20 eV) in an isolated C60 and C70 fullerene molecule followed by ejection of a single energetic electron leaving the molecule intact.
