Definitions:

Splitting

A phenomenon observed in NMR spectroscopy where a signal is divided into multiple peaks due to interactions between nuclear spins.

Signals

In spectroscopy, the representations of energy interactions with samples, providing information about molecular structure.

Quartet

In NMR spectroscopy, a signal split into four peaks of specific intensity ratio, indicating the influence of three equivalent nuclei on the observed nucleus.

Spin-Spin Splitting

A phenomenon in nuclear magnetic resonance (NMR) spectroscopy where nuclear spin states interact, leading to multiple peaks for a single nucleus.
