Abstract:
We have identified and examined the excited state of the cluster-solvated, valence-bound acetonitrile anion dimer, consistent with recent experimental findings, determining that the cluster excited state is of predominantly single-excitation character. Potential energy surface scans in coordinates specific to a "dissociative" normal mode common between the excited and ground states of the valence anion as well as the ground-state neutral dimer species shed light on the proposed vibrational autodetachment mechanism, with calculated excited-state lifetime consistent with experiment.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
