Definitions:

NMR Spectrum

A depiction of the nuclear magnetic resonance of atoms within molecules, providing detailed information about the structure, dynamics, and environment of the molecule.

C-13 NMR

A type of nuclear magnetic resonance spectroscopy that focuses on the detection of carbon-13 isotopes to determine the structure of organic compounds.

Off Resonance Splitting

A phenomenon in NMR spectroscopy where the splitting of signal occurs away from the resonance frequency due to interactions with neighboring atoms.

H-NMR Spectra

The set of signals obtained in hydrogen-1 nuclear magnetic resonance spectroscopy, which provides information on the molecular structure, especially about the environment of hydrogen atoms in a compound.
