Abstract:

Trapped, solvated electrons in primary, secondary and tertiary amine glasses have been studied by EPR and ENDOR to deduce aspects of the geometrical structure of the amines around the electrons. NH deuteration experiments show no effect on the EPR and ENDOR linewidths of trapped electrons in primary and secondary amines and indicate that the alkyl protons are closer than the NH protons to the electron. The trapped electron EPR linewidths are larger in primary and secondary amines approx. 7G than in tertiary amines approx. 4G which suggests a small contact hyperfine coupling this is supported by ENDOR data. In tertiary amines EPR and ENDOR results on trapped electrons suggest that the proton interaction is purely dipolar and that the closet protons are 3.4 A from the electron. In the more polar primary and secondary amines the small proton contact interaction suggests that the closet protons are 3.4 A from the electron. Author
