High-resolution ESR. spectra of the radicals CH2COOR, CH3CHCOOR and (CH3)ZCCOOR with R = CH3, CH2CH3, CH (CH,), and C (CH,), in liquid solution confirm planar energy-minimum structures with substantial barriers to internal rotation about the C, CO-bonds (-40 kJ/mol) and partial n-electron delocaliza
## Abstract Solution and powder ESR spectra of the 4‐trifluoromethyl‐1,2,3,5‐dithiadiazolyl and 4‐pentafluorophenyl‐1,2,3,5‐dithiadiazolyl free radicals were analysed. Comparison of the ESR parameters with those obtained for the protonated equivalents shows that fluorination produces a drift of unp
Shortly after their formation, transient free radicals trapped in micelles exhibit electron spin resonance (ESR) spectra with "antiphase" lineshapes, i.e. lines with their low-field halves in emission and high-field halves in absorption. It is demonstrated that this hitherto unexplained effect is co
