Abstract:
The transition state region for neutral hydrogen transfer reactions can be accessed by photodetachment of a stable neg. ion with a geometry similar to that of the neutral transition state. In this work the SH + H2S and SD + D2S reactions are investigated by photodetachment-photoelectron spectroscopy of HS-·H2S and DS-·D2S. The spectra exhibit vibrational structure which is attributed to the antisym. stretching mode (H-atom motion) of the neutral transitions state for H-atom transfer. The spectra...     »
