KINETIC STUDY OF THE REACTION OF CYTOSINE TAUTOMERIZATION IN THE GAS PHASE

Eight tautomers of cytosine have been studied by ab initio methods in the gas phase. Thestudy of reactive chemical processes on a molecular level requires knowledge of the potentialenergy surface (PES) for the system considered. The nature of PES can be probed eitherexperimentally or by using ab initio quantum chemical calculations. In this study we havereported one dimensional PES for all trajectories of the reaction of cytosine tautomerizationin the gas phase.
