While fluorescence can be clearly observed in resonance-stabilized acyclic anions, its occurrence is insufficient for unambiguous assignment of either ion-pairing type or anion geometry. As. in cyclic, aromatic anions, the requirement for contact ion-pairing is less severe in the excited state than
## Abstract __Ab initio__ STO‐3__G__ calculations show that α‐cyano‐ and α‐isocyano‐substitution on carbanions produce a significant approximately equal stabilization of these charged species. Evidence is presented which suggests that the mechanism of such stabilization is qualitatively different f
