## Abstract Proton‐hyperfine data are reported for the radical anions generated from azulene (1) and its alkyl derivatives 2–11 in 1,2‐dimethoxyethane both ‘chemically’ with K and electrolytically. The alkyl derivatives are 1,3‐dimethyl‐ (2), 5,7‐dimethyl‐ (3), 1,3,5,7‐tetramethyl‐ (4), 2‐methyl‐ (

## Abstract The ENDOR spectrum was obtained for the benzo[__c__]cinnoline anion radicalin 1,2‐dimethoxyethane. The hfs constants of the protons correspond with those found by EPR spectroscopy, and also agree well with the qualitative tendency of the reported spin density distributions by HMO calcul
## Abstract Radical anions often monocyclic and bicyclic azoalkanes containing the azo group in (__Z__)‐conformation, have been fully characterized by their hyperfine data with the use of ESR, ENDOR, and general‐TRIPLE‐resonance spectroscopy. These azoalkanes are represented by 3,3,5,5‐tetramethyl‐
