Observation of a core-excited dipole-bound state $\sim$1 eV above the electron detachment threshold in cryogenically cooled acetylacetonate

Dipole-bound states in anions exist when a polar neutral core binds an electron in a diffuse orbital through charge--dipole interaction. Electronically excited polar neutral cores…
