摘要

We have recently shown that negative ion photodetachment can be used toinvestigate the transition state region of a neutral bimolecular reaction. In our experiments, the spectroscopy and dissociation dynamics of the short-lived AHB complex formed during the hydrogen transfer reaction A + HB to HA + B are studied via photoelectron spectroscopy of the stable, hydrogen-bonded anion AHB(-). Thus far, results have been reported for the symmetric hydrogen transfer reactions Cl + HCl, I+ HI, and Br + HBr which were investigated by photodetaching the negative ions ClHCl(-), IHI, BrHBr, respectively. The photoelectron spectra of these ions show resolved vibrational progressions assigned to the unstable neutral complex associated with the corresponding bimolecular reaction. Our analysis as well as simulations of these spectra by other investigators has shown that this vibrational structure provides a sensitive probe of the neutral potential energy surface near the transition state.
