Abstract
- Abstract: Structure of radical anions of “bridged” amidoesters MeOOC(CH2) n CONMe2 (n=0–3) generated by X-ray irradiation was investigated by EPR, optical absorption spectroscopy and quantum-chemical calculations. Amidoester-0 (n=0) has positive calculated electron affinity and the corresponding delocalized radical anion is stabilized independent of matrix polarity. Meanwhile, for amidoesters with n=1–3 groups possessing apparently negative intrinsic electron affinity the role of matrix in stabilization of the corresponding radical anions becomes crucial. Two types of the localized radical anions were observed in the latter case. [Copyright &y& Elsevier]
