Basic 1h- And 13c-nmr Spectroscopy -

NMR provides a direct look at the carbon skeleton of a molecule.

: In a strong external magnetic field, these nuclei align either with ( state ) or against ( state ) the field. Basic 1H- and 13C-NMR Spectroscopy

: Applying radiofrequency (RF) energy causes nuclei to "flip" between these states. The energy required depends on the electronic environment surrounding the nucleus, a phenomenon known as shielding . NMR provides a direct look at the carbon
