Definitions:

Triplet

A signal in NMR spectroscopy that is split into three peaks, suggesting an atom's hydrogen atoms are coupled to two equivalent neighboring hydrogens.

Broad Singlet

A NMR signal appearing as a single peak but broader than typical singlets, often resulting from molecules with rapid internal motion.

NMR Data

Information obtained from nuclear magnetic resonance spectroscopy, used to determine the structure and dynamics of molecules by examining the environment of nuclear spins.

Quartet

A term used in NMR spectroscopy referring to a signal split into four peaks due to coupling with three equivalent neighboring nuclei.
