Multiphoton Ionization and Fragmentation of Hydrogen Chloride: A Diatomic Still Good for a Surprise
Figure 5
Path III: the fastest observed H+ ions are produced from autoionization of superexcited HCl** to HCl+() with , followed by photodissociation of HCl+() by absorption of a fourth photon. The kinetic energy of the observed H+ fragment is determined in the fourth photon absorption step. The colour coding matches that of Figure 3.
