title: Spectral data analyses and structure elucidation of metoprolol tartrate.
abstract: The infrared spectrum, ultraviolet spectrum, mass spectra, and nuclear magnetic resonance spectra of metoprolol tartrate, an antiarrhythmic medicine, were reported and interpreted comprehensively. The vibrations of functional groups in infrared spectrum, electron transitions in ultraviolet spectrum, and main characteristic fragmentations in mass spectra of metoprolol tartrate were discussed. All the (1) H and (13) C NMR chemical shifts were assigned by means of distoritionless enhancement by polarization transfer-135 and -90, (1) H-(1) H correlation spectroscopy, and (13) C-(1) H correlation spectroscopy via short- and long-range coupling.
