Ultrafast reaction dynamics in cluster ions: Simulation of the transient photoelectron spectrum of I2 Arn photodissociation
The photodissociation and recombination of a dihalide ion embedded in a cluster illustrates the crucial role played by the solvent in chemical reactions that involve charged species. In these strongly interacting systems, the solvent does not merely interrupt and redirect motion on the potential energy surfaces of the isolated molecule, it profoundly modifies the surfaces themselves. As the dih...
متن کامل–Arn cluster ions
We investigate the photodissociation, geminate recombination and relaxation dynamics in size-selected I2 2 •Arn cluster ions using a coupled quantum-classical molecular dynamics method and a model Hamiltonian gained from diatomics-in-ionic systems. We calculate photofragmentation yields of various charged product clusters of the dissociated I•Arf or recombined I2 2 •Arf 8 forms as a function of...
متن کاملPhotodissociation of I2(OCS)n Cluster Ions: Structural Implications
We report product distributions from the photodissociation of I2(OCS)n (n ) 1-26) cluster ions at 790 and 395 nm and discuss implications concerning the structure of these clusters. The experimental results are paralleled by a theoretical investigation of I2(OCS)n structures. The 790 and 395 nm transitions in I2 access dissociative excited states that correlate with the I+ I(P3/2) and I+ I*(P1/...

متن کاملFormation, photodissociation and structure of chromium/phosphorus binary cluster ions
Chromium/phosphorus binary cluster ions, [Cr(n)P(m)](+/-), produced by laser (532nm) ablation on a tablet of well-mixed chromium and red phosphorus powder, were studied with a home-built tandem time-of-flight (TOF) mass spectrometer. The clusters thus formed are mostly rich in phosphorus. There is an odd-even oscillation in the intensity of the [CrP(m)](+) series, i.e. the mass peaks of even m ...
