Multiphoton Ionization and Fragmentation of Hydrogen Chloride: A Diatomic Still Good for a Surprise
Figure 3
Velocity map image of H+ ions generated by competing dissociation and ionization processes following two-photon excitation of the line of the () band at 236.000 nm. Shown are the two-dimensional meridian projection and matching one-dimensional speed distribution obtained from the fully three-dimensional (3D) momentum vector distribution of H+ ions observed by the 3D velocity map imaging (3DVMI) technique. The colour coding of the speed distribution assigns the observed H+ ions to the three fragmentation pathways discussed in the text (blue/slow: path I, red/medium: path II, green/fast: path III).
