Title: Nonadiabatic Chemical Reaction Triggered by Electron Photodetachment: An Ab Initio Quantum Dynamical Study

Research: Scientists investigated the dynamics of a chemical reaction triggered by electron photodetachment in a complex of a chloride anion with ammonia.

Methodology: They used a combination of electronic structure and quantum dynamical methods to characterize the reactive and nonreactive channels of this process.

Key Findings:

The reaction involves a nonadiabatic proton transfer from the ammonia molecule to the chloride ion, leading to the formation of an HCl molecule and a NH2 radical.
The excited charge-transfer state of the complex, prepared by vertical electron photodetachment, is the main channel for this reaction.
* The reaction is essentially a one-dimensional process, involving a collinear motion of the hydrogen atom between the chloride and nitrogen atoms.

Conclusion: This study demonstrates a new class of chemical reactions triggered by electron photodetachment, where a nonadiabatic process leads to the formation of new chemical species. The results provide a benchmark for investigating this type of reaction and shed light on the underlying mechanisms.
