The effect of N-heteroatoms and CH3 substituents on dissociative electron-ion recombination of protonated single six membered ring compounds at room temperature

► Protonated ring rates increase with number of nitrogens within the ring. ► Protonated ring rates decrease with the number of methyl additions. ► Proton bound ring dimers have the opposite effect of the protonated forms. ► Isomeric form has little effect on the rate.
