Collisional Activation, charge-stripping and neutralization/reionozation mass spectra allow the identification of six [C6H7N]+· isomers, namely the molecular ions of the three isomeric picolines, 1+·-;3+·, ionized 2- and 4-methylene dihydropyridines, b - c, and ionized pyridinium methylide, a. The implication of the distonic forms a and b in some fragmentation reactions of funct of onalized (position 2) pyyridines is briefly discussed. Molecular orbital calculations indicate the b〉a〉1+· stability sequence.
