Clustering and multiphoton effects in velocity map imaging of methyl chloride
Original language description
We have investigated different effects caused by clustering and multiphoton processes in the photodissociation of CHCl using velocity map imaging (VMI). Single-photon dissociation of CHCl at 193.3 nm yields CHand Cl fragments probed subsequently by resonance enhanced multiphoton ionisation (REMPI) at 333.52 nm and 235.31 nm, respectively. In the clusters, the CHfragments are strongly 'caged' losing most of their kinetic energy. Consequently, the VMI is dominated by a sharp central peak. On the other hand, the Cl fragments lose a broad range of energies in the cluster, yielding a blurred isotropic 'central blob' in VMI. At an increased 193 nm photon flux, another central feature appears in the CHimages for isolated CHCl molecules. This 'hour-glass' shaped image corresponds to the CHCl multiphoton ionisation at 193 nm and subsequent CHClion photodissociation at 333 nm. The ion photodissociation is a parallel process with the anisotropy beta-parameter values between +1.3 and +2.0. The total kinetic energy release (TKER) distribution suggests a high CHvibrational excitation. The CHClion photodissociation is discussed and compared to the photodissociation of similar CHBrion.
