Abstract

We report the formation of demethylation in 3-methyl-uracil (3meU) and 1-methyl-thymine (1meT), i.e. (3meU-CH3)(-) and (1meT-CH3)(-), through potassium-molecule collisions at different potassium kinetic energies. Study of the threshold of formation of this fragment can provide a value of threshold energy that can be compared with DEA studies.
