Theoretical studies of Mefenamic Acid Polymorphs: Solid-state 13C carbon-NMR and vibrational (IR and Raman) Spectroscopies.

The two polymorphs of mefenamic acid (MEF) or 2-[(2,3-(dimethyphenyl)amino] benzoic acid polymorphs (known as I and II forms) were studies in the framkework of density functional theory (DFT). The DFT calculations were performed using the Gaussian03 package and these results were compared with experimental data of solid-state 13C Nuclear Magnetic Resonance (NMR), vibrational Raman and infrared spectroscopies.CAPESCNPqFAPES
