C NMR spectra provide a wealth of structural information that is useful to synthetic chemists. Selection of the appropriate 1D and 2D NMR experiments can enable the connectivity and geometry of the molecule to be assigned.
Reserpine: COSY showing the proton coupling network within the molecule
Reserpine: Dept-edited HSQC showing 1-bond carbon-proton interactions
(-)-Cinchonidine: ROESY showing through space interactions
Strychnine: COSY showing the proton coupling network within the molecule
Strychnine: HMQC showing 1-bond carbon-proton interactions
Strychnine: HMBC showing carbon-proton interactions over several bonds
