Theoretical calculations applied to the study of the energetics of reactions of methamphetamine synthesis and to the characterization of reactants, products and by-products

Density Functional Theory (DFT) was used to perform quantum chemical calculations at B3LYP level, with the 6-31G** basis set, as implemented by the Spartan computer program. The entities studied are the reaction of synthesis of MDMA (3,4, methylene dioxymethamphetamine), and a number of analogs of methamphetamine. The analogs have also been geometry-optimized and their infrared vibrational frequencies were calculated.
