Abstract.

The laser-induced intracluster Ba..FCH3+ hν → Ba* + CH3F photofragmentation has been investigated in the 13158–13736 cm-1 energy range, corresponding to the electronic Ã′-state of the Ba..FCH3 molecule. The major photofragmentation path was found to be the non-reactive Ba* + CH3F channel. The photodepletion action spectrum of the Ba..FCH3 was measured using nanosecond pump and probe technique, showing a broad feature with a maximum photodepletion cross-section of 8 Å2. The action spectrum of the non-reactive Ba photofragmentation channel was also measured. The results are discussed in the light of a proposed mechanism for the harpooning reaction leading to BaF when the complex is excited to the à electronic state.
