NMR SPECTROSCOPY

NMR SPECTROSCOPY. Introduction. NMR srectroscopy is the study of spin changes at the nuclear level when radio frequency energy is absorbed in the presence of magnetic field. Nuclei with odd mass number only Nuclei with odd mass number only give NMR spectra.

All of the signals are recorded as singlets . 13 C - 13 C splitting is not observed

All of the signals are recorded as singlets . 13 C - 13 C splitting is not observed 13 C - 1 H splitting is suppressed with a technique called broadband decoupling. The signal intensity is not proportional to the number of 13 C giving rise to the given signal.
