The laser-induced intracluster Ba··FCH3+ 
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.
