Spectroscopic studies, potential energy surface and molecular orbital calculations of pramipexole

Pramipexole is one of the newer drug approved for the treatment of Parkinson disease. Parkinson disease (PD) is a neurodegenerative disorder characterized by bradykinesia, rigidity postural imbalance and tremor. Theoretical and experimental vibrational spectroscopic research gives a correct assignment of the fundamental bands in FT-IR and FT-Raman spectra.
