    We report solid-state NMR characterization of the 17O quadrupole coupling (QC) and chemical shift (CS) tensors in five site-specifically 17O-labeled samples of salicylic acid and o-acetylsalicylic acid (Aspirin). High-quality 17O NMR spectra were obtained for these important pharmaceutical compounds under both static and magic angle spinning (MAS) conditions at two magnetic fields, 14.0 and 21 ...

  • Aspirin Synthesis Lab Analysis - Odinity

    This gas was acetic acid; an end product in the aspirin synthesis reaction, thus the NMR spectrum of acetic acid was analyzed. It is known from the NMR spectrum of acetone, which is a reference compound with only one type of hydrogen (that belonging to CH 3 ), that the peak at 2 PPM in the acetic acid spectrum pertains to CH 3 (table 2.3).
