Photodissociation Spectroscopy and Dynamics of Weakly Bonded Metal Ion—Ethylene Complexes

Abstract

The photodissociation spectroscopy of weakly bonded bimolecular complexes can give important insight into fundamental molecular interactions and dynamics. We have applied these techniques to a study of metal ion-ethylene interactions in the Mg\3s)-C2H4and At(3s 2)-C 2H4 rt-bonded complexes. Experimental work is supported by ab-initio electronic structure calculations. These experiments allow us to explore and compare the chemical binding, electronic structure, and nonadiabatic dissociation dynamics of these complexes.
