Photochemistry of HI on argon and water nanoparticles: Hydronium radical generation in HI(H(2)O)(n)
Original language description
Photochemistry of HI molecules on large Ar(n) and (H(2)O)(n), (n) over bar similar to 100-500, clusters was investigated after excitation with 243 nm and 193 nm laser radiation. The measured H-fragment kinetic energy distributions pointed to a completelydifferent photodissociation mechanism of HI on water than on argon clusters. Distinct features corresponding to the fragment caging (slow fragments) and direct exit (fast fragments) were observed in the spectra from HI photodissociation on Ar(n) clusters. On the other hand, the fast fragments were entirely missing in the spectrum from HI center dot(H(2)O)(n) and the slow-fragment part of the spectrum had a different shape from HI center dot Ar(n). The HI center dot(H(2)O)(n) spectrum was interpreted interms of the acidic dissociation of HI on (H(2)O)(n) in the ground state, and hydronium radical H(3)O formation following the UV excitation of the ionically dissociated species into states of a charge-transfer-to-solvent character.
