The kinetic energy release in the photodissociation of (n = 1–10) clusters at photon energies from 0.43 to 4.66 eV

Photodissociation dynamics of hydrated aniline cluster cations, aniline ( H 2 O ) n + (n = 1–10) was investigated in the infrared and UV–visible region focusing on the kinetic energy release (KER). In case of infrared photodissociation at 0.43 eV, the KER was independent of the cluster size while it was clearly size-dependent at UV–visible energies. The excitation of different vibrational modes had no effect on the KER despite that the internal energies of the parent ions were different. The KER increased from 53 to 160 meV for aniline ( H 2 O ) 1 + cluster with increase in the photon energy from 0.43 to 4.66 eV.
