2-, 3-, 4-Pyridylmethyl(picolyl) radicals have been prepared in fluid solution by hydrogen or halogen abstraction from the corresponding hydride or chloride.The weak e.s.r. spectra have been analysed by improved correlation methods: results agree with INDO calculations about as well as do those for benzyl radicals.All three radicals have higher spin density at the α-position than does benzyl: the order is 4 > 2 > >3 > benzyl.Improvements in correlation techniques required for this analysis include a method for finding the centre of a spectrum without prior determination of the coupling constants, and MULTIPEAK, a method of establishing new coupling constants, which uses the whole information available in the spectrum and which is particularly useful in the analysis of spectra with numerous doublet splittings.
