Comparative study of the vibrational optical activity techniques in structure elucidation : the case of galantamine [PDF]
, 2019 The absolute configuration of the alkaloid galantamine was studied using a range of solution-state techniques; nuclear magnetic resonance (NMR), vibrational circular dichroism (VCD), and Raman optical activity (ROA). While the combined use of NMR and VCD
