Anion Photoelectron Spectroscopy

The anion photoelectron spectrum of the bromide–carbon monoxide complex is presented in combination with supporting ab initio calculations. The spectrum features transitions between anion and neutral van der Waals complexes, Br⋯CO. A stabilization energy of 0.14 ± 0.05 eV is extracted from the spectrum, while the predicted binding energy for the anion complex is 9.9 kJ mol–1 from CCSD(T)/aug-cc-pVTZ calculations. The electron affinity of the Br⋯CO complex is 3.50 ± 0.05 eV. The ab initio calculations reveal a previously unreported minimum for the neutral radical complex, namely the van der Waals Br⋯OC linear complex.
