The <SUP>13</SUP>C spectrum taken during the reaction of 4-picoline <I>N</I>-oxide with acetic anhydride at 110 °C in the NMR cavity (23.5 kG) shows a pair of emission lines at 15.8 and 154.4 ppm and enhanced absorption at 29.6 and 125.0 ppm (TMS-based). The signals are found to be due to 4-ethylpyridine formed as a minor product of the reaction and are interpreted in terms of the memory effect of the polarization induced in the precursor 4-picolyl-acetoxy radical pair.
