H and 13C NMR chemical shifts of a series of 1 -substituted pyridinium salts were measured in dimethyl sulfoxide. The effect of the quaternary pyridinium ring on the resonance of the methylene group of the substituent is reported. Increments of 6'H = 3.89 f 0.1 6 ppm and 6' 3C = 47.5 f 3.7 ppm are e
