Definitions:

Proton Spin Decoupled

A technique used in NMR spectroscopy where the coupling between proton spins is removed, simplifying the spectrum and making it easier to interpret.

Peaks

In analytical chemistry, refers to the points in a graph, spectrum, or chromatogram that represent a maximum concentration or abundance of a compound or component.

Compound

A substance formed from the chemical combination of two or more elements in a specific ratio, bonded together in a fixed structure.

Proton Spin Decoupled

A technique in nuclear magnetic resonance (NMR) spectroscopy where the interaction between proton spins is removed or reduced to simplify the spectrum and enhance structural elucidation.
