| Popis: | The natural-abundance ^(13)C magnetic resonance spectra of nicotine, quinine, several Amaryllidaceae alkaloids, and selected derivatives of these have been determined at 15.8 MHz. With the aid of proton decoupling techniques and the shifts which occur on formation of specific derivatives, it has been possible to make self-consistent and unambiguous assignments of nearly all the resonances for these alkaloids. |
