The structure shown in the figure above is found in which one of the following?
Definitions:
Quartet
A signal in NMR (Nuclear Magnetic Resonance) spectroscopy indicating the presence of three equivalent protons coupled to the observed nucleus, typically resulting in a pattern of four peaks.
Singlet
A term in spectroscopy describing a state with all electron spins paired, resulting in no net electron spin.
NMR Data
Information derived from nuclear magnetic resonance spectroscopy, providing insights into the molecular structure, dynamics, reaction state, and chemical environment of molecules.
Doublet
A pattern, especially in spectroscopy, where a signal is split into two components with a small separation, indicating the interaction between nuclear spins.
