Transition State Spectroscopy of Hydrogen Transfer Reactions

Abstract

The transition state region for several chemical reactions of the type A + HB yields HA + B has been investigated via photodetachment of the stable negative ion AHB-. The photoelectron spectra of BrHBr- and BrHI- show resolved vibrational structure attributable to the transition state region of the Br + HBr and Br + Hi reactions, respectively. The photoelctron spectra of IDI- and the cluster ion IDI-(N2O) are compared; these spectra probe different parts of the I + HI potential energy surface. Finally, a high resolution threshold photodetachment spectrum of one of the IHI- features shows evidence for reactive resonances in the I + HI reaction. (KT)
