Abstract
ENDOR and ESR spectra of the 2‐(p‐Dimethylaminophenyl)indan‐1,3‐dione‐2‐yl radical were measured in toluene and diethyl phthalate at 350 K. A solvent dependence of the coupling constants was observed. Using the MNDO method, the optimized structure of the radical and the spin population distribution were derived.
