Definitions:

Doublet

A pair of closely spaced lines or signals observed in spectroscopy, indicating the splitting of a spectral line into two components.

NMR Data

Data derived from Nuclear Magnetic Resonance spectroscopy, utilized to identify the configuration of molecules.

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.
